It's not a common setup mistake. Nothing changed in this release and
this has never been reported before.
The behaviour to wait for pg_stop_backup() was added by user request.
The behaviour for shutdown to wait for pg_stop_backup() was also added
by user request.
Your mistake was not typoing an archive_command, it was not correctly
testing that what you had done was actually working. The fix is to read
the manual and correct the typo. Shutting down the server after failing
to configure it is not likely to be a normal reaction to experiencing an
error in configuration. Better docs might help you, but I doubt it.
ISTM you should collect test reports, then analyse and prioritise them.
This rates pretty low for me: low severity, low frequency.
(If new users panic when they can't do shutdown the server, they
probably won't like smart shutdown very much either.)
