I think we do not need a recipe for Babel anymore.
If something really needs to be installed in hostpython3, for any reason, we likely need to do that in another way.

What do you think about it?

[RobertFlatt]

I really don't know what people use for this.
I do know that nobody is using Babel on Android because it broken.
Go ahead kill it, worst case we have to bring it back.

Even if may not be the lightweight solution, I use that to format dates based on the user locale on Android and iOS apps.

Unfortunately, I never encountered the build issue, since I pinned a specific version since the introduction on my codebase.

Go ahead kill it, worst case we have to bring it back.

When it comes to cleaning code, I do not think twice.

Fixed via #2826
