You are right that you can't force a particular library's maintenance
team to do something. That does not necessarily mean that people would
not come together to make changes benefitting Boost in general.

I have seen the calls for that from users. The general objection is that
downloading/installing monolithic Boost when only a few libraries are
needed "seems" wrong.

No. I still believe that things can be done by consensus. Recently a
'meta' directory with some information was added to all Boost libraries.
I did not see any uprising against this. So clearly it is possible.
