Speaking only for myself as an author of a Boost library, maintainer
of many Boost libraries, and contributor to many Boost libraries,  as
well as being involved in the Boost release process:

1. Based on my personal knowledge of Boost users, as well as e-mails
to the Boost developers lists (boost_at_...), and the Boost Owners  lists
(boost-owner_at_...) from users such as:
   -    @us.af.mil  (US Airforce)
   -   @nasa.gov  (NASA)
  and others

I would not be in favor of a Boost distribution that requires anything
higher than C++11 for existing libraries. i.e. Not C++17 or even
C++14.

2. Based on first hand accounts of certain users choosing not to
migrate to C++20 because of a silently breaking change in the language
affecting their code (operator== rewriting rules, which has even
broken certain Boost libraries like Rational), I would certainly not
be in favor of changing existing Boost libraries to require C++20 for
anything in an official Boost distribution.
