"[...], if the role was granted WITH SET TRUE [...]"
That seems to be the important part of your RFTM answer, which is
apparently new in v16.
There also seems to an override:
https://www.postgresql.org/docs/16/runtime-config-client.html#GUC-CREATEROLE-SELF-GRANT
"createrole_self_grant (string)
If a user who has CREATEROLE but not SUPERUSER creates a role, and
if this is set to a non-empty value, the newly-created role will be
granted to the creating user with the options specified. The value must
be set, inherit, or a comma-separated list of these. The default value
is an empty string, which disables the feature.
The purpose of this option is to allow a CREATEROLE user who is not
a superuser to automatically inherit, or automatically gain the ability
to SET ROLE to, any created users. Since a CREATEROLE user is always
implicitly granted ADMIN OPTION on created roles, that user could always
execute a GRANT statement that would achieve the same effect as this
setting. However, it can be convenient for usability reasons if the
grant happens automatically. A superuser automatically inherits the
privileges of every role and can always SET ROLE to any role, and this
setting can be used to produce a similar behavior for CREATEROLE users
for users which they create.
