Not that it's less than the supported upgrade path.

That's a fair argument. However:

1. Does deprecation really mean anything in terms of profiles? Even
in the context of EAPI bans we explicitly stated that it affects new
packages and EAPI bumps. I think deprecating it for ebuilds is still
meaningful even if profiles would stay EAPI 5.

2. Do we want to keep profiles EAPI 5 indefinitely? If we consider it
a goal to reduce the number of EAPIs in use, I think it would be
reasonable to bump profiles to EAPI 6 proactively, even if it doesn't
change anything.
