I marked ReplaceMenuProvider#_getAdHocHeaderEntries as deprecated, but since it's internal and not used anywhere else, can I just remove it?

Yes. What starts with _ is internal and can be removed at any time.

The code looks good, and the solution works great from the user perspective. I wonder why we have not implemented it this way in the first place :D
