But then most likely not based on Accept-Encoding but other headers such
as User-Agent or the source IP...

In any event I fully agree that it's then the responsibility of whatever
that set the no-gzip flag to also add a proper Vary attribution to the
response.

Only if no-gzip is set unconditionall should Vary not be added by the
one setting no-gzip. But it's acceptable (even if not 100% correct) to
not add Vary when setting no-gzip if one then accepts that the
uncompressed variant ay get sent to more clients by downstream cache
servers.
