--- Comment #1 from Damien Miller <djm at mindrot.org> ---
Yes, unfortunately this incompatibility is an unavoidable price of
better quoting semantics.

The incompatibility and the same workaround you arrived at were
mentioned in the openssh-9.9 release notes:

> * ssh(1), sshd(8): processing of the arguments to the "Match"
>   configuration directive now follows more shell-like rules for
>   quoted strings, including allowing nested quotes and \-escaped
>   characters. If configurations contained workarounds for the
>   previous simplistic quote handling then they may need to be
>   adjusted. If this is the case, it's most likely to be in the
>   arguments to a "Match exec" confition. In this case, moving the
>   command to be evaluated from the Match line to an external shell
>   script is easiest way to preserve compatibility with both the old
>   and new versions.

We don't plan to make further changes to Match argument handling.
