OK, I'll try to help, but I don't know what Google or Gmail will do in
the future, in general, obviously.  I wanted this bug report to be
specifically about Gnus, IMAP and OAuth 2.0 (which the responding
experts correctly inferred was more precisely about Gnus, IMAP and
Gmail's proposed OAuth 2.0 policy change).

Your question reminded me that Gmail provides "basic HTML view" which
does not require any Javascript whatsoever for sign-in or for the main
interface, and thus is fully useable with Emacs Web Wowser (eww).  For
me that isn't a viable alternative to Gnus, so it's tangential to this
bug report, but that access method is feasible using entirely Free
Software.  Hopefully that answers your question.

Will "basic HTML view" still be available after Gmail starts mandating
OAuth 2.0 for IMAP access (assuming they do, sometime in the future)?  I
suspect it will, but I don't know.
