Oh, sorry, I suppose all the rather personally oriented debate

Speaking personally, it would be more accurate to say that now that
the issue has (practically) been decided I may have a better chance of
finding time to update the manpages to document setgid directories and
BSD semantics.  I don't have to spend quite so much time debunking
what I see as spurious arguments against the IMO reasonable course
that's now being taken (modulo problems with the default).

When I've seen 0.92 I'll write an admin supplement for it, unless
someone would rather do it. (please!)

I firmly believe - and have much evidence for doing so - that even if
the fact that user private groups are in use (assuming they are by
default - please let them be!) is documented nowhere else but
adduser(8) and /etc/adduser.conf then there will be at the very most
very few problems, and that even those will be minor.

If it's not the default then IMO some documentation will be needed to
tell people to turn the option on so that they do not end up with e.g.
/usr/local/man trees with bizarre and inconsistent permissions, and so
that forthcoming software for management of groups by ordinary users
will actually work properly for all users.

However, this issue is certainly something that should be covered in a
section of the Debian Administrators' Supplement, along with security
policy in general.
