Thank you very much for doing this. I agree that making the obsolete options
undocumented makes sense - I’d love to remove them, but there are downstream
build recipes that use them.
I did not spot any descriptions that looked off.
So OK for trunk,

P.S. — are there any outstanding documentation queries that I need to
resolve? (just getting back to general maintenance after C++y things)
