Got an AS0018 error when deleting an empty, but before renumbered table extension which contains a public procedure.

[SSZurmussen7112]

1. Describe the bug
In our AppSource application we had to renumber some table extensions to solve possible ID conflicts with other apps. In a first step I made a copy of the table extension object file, changed the ID and name of it and deleted all fields and procedures from the original table extension. In this first step, it was not possible to delete the original and empty table extension, but we were able to release the app without any breaking changes.
We released this app and after that, I was able to delete the old, empty table extensions without getting any error. But when the table extension contains at least one public procedure, I get an AS0018 error:
error AS0018: Procedure 'CCSMyProcedure()' has been removed in 'TableExtension CCS My Table'. A procedure that belongs to the public API must not be removed as it will break dependent extensions calling this procedure.

2. To Reproduce
Steps to reproduce the behavior:

1. Create a tableextension with a new field and a public procedure, like this:

tableextension 5013400 "CCS DM MyOriginalTablExtension" extends "Sales Line"
{
    fields
    {
        field(5013400; "CCS DM My Description"; Text[100])
        {
            Caption = 'My Description';
            DataClassification = CustomerContent;
            ToolTip = 'Specifies a custom description for the sales line.';
        }
    }

    procedure CCSDMGetMyDescription(MyDescription: Text[100]): Text[100]
    begin
        exit(MyDescription);
    end;
}

2. Release the app with version 1.0.0.0 and use this app version in the AppSourceCop.json: "version": "1.0.0.0"
3. Increase the version in the app.json to 2.0.0.0
4. Make a copy of the table extension and change the ID and the name. Then delete the fields and procedure in the original object:

tableextension 5013400 "CCS DM MyOriginalTablExtension" extends "Sales Line"
{
}

tableextension 5013401 "CCS DM MyOriginalTablExt 2" extends "Sales Line"
{
    fields
    {
        field(5013400; "CCS DM My Description"; Text[100])
        {
            Caption = 'My Description';
            DataClassification = CustomerContent;
            ToolTip = 'Specifies a custom description for the sales line.';
        }
    }

    procedure CCSDMGetMyDescription(MyDescription: Text[100]): Text[100]
    begin
        exit(MyDescription);
    end;
}

5. Release the app with version 2.0.0.0 and use this app version in the AppSourceCop.json: "version": "2.0.0.0"
6. Increase the version in the app.json to 3.0.0.0
7. Delete the old and empty tableextension 5013400. Error AS0018 appears!

3. Expected behavior
I expected that the old and empty table extension can be deleted. The described process already works if the table extension only contains fields or local and internal procedures. But if it contains at least one public procedure, the process does not work.

4. Actual behavior
The AppSourceCop and compiler gives an error:
Procedure 'CCSDMGetMyDescription()' has been removed in 'TableExtension CCS DM MyOriginalTablExtension'. A procedure that belongs to the public API must not be removed as it will break dependent extensions calling this procedure.

Unfortunately, there has been no response to my entry yet.

But to move forward, I have now moved the procedure CCSDMGetMyDescription() back to the old table extension, but marked it as obsolete there. After the next app release, it will then be possible to delete the old table extension and transfer the procedure in question to the new table extension.

But in my opinion the behavior of the compiler is still wrong.
