A bunch of other folks have already annotated "internal" APIs, and added entries to 
libabigail.abignore to suppress warnings. If you are 100% certain these are never used 
by end applications, you could do likewise.

That said, depreciation notice and completing in 20.11 is definitely the better approach.
