I'm filing this issue to track the finalization of the contribShareMenu API proposal since I was not able to find a tracking issue, cc @alexr00.

Current state

The contribShareMenu API proposal tracks the following menu points:

• file/share
• editor/context/share

This proposal has been in place for several months without changes, and was previously discussed in #146309 and #157722, but has not yet been finalized. This means it can't yet be used by most extensions, limiting its utility. An example of an extension that IMO would be a great fit for the Share submenus is Live Share (cc @jramsay):

Additional share submenus

As part of #175676 I'm looking at integrating link sharing more deeply into our product surface area, with the goal of making collaboration via links as seamless as possible. Therefore I'm proposing to expand this API proposal to also include

• editor/title/context/share
• explorer/context/share

(Note, there is also editor/lineNumber/context via #175945, but I have not added a share submenu for that context menu yet because we are introducing that context menu for the first time all up and it would be odd to only have one item in the menu which is itself a submenu.)
