The OP is asking for official OpenSSH portable 8.8 (circa 2021-09-26)
sftp clients to behave better when talking to official OpenSSH 8.0
(circa 2019-04-17) portable sftp servers.  Red Hat has nothing to do
with the request, except for the fact that a RHEL8 system is where the
OP is encountering the OpenSSH 8.0 sftp server.

This request is neither rude nor outrageous.  The OP asked politely,
and attempted to do most of the work.

It is not.  Not everyone has the ability to upgrade every host to the
latest version of OpenSSH client/server.  Both backwards and forwards
compatibility are desirable things.

That is, quite literally, *exactly* the case the OP made.
