My main worry is that you've got a dictionary cache.
Updating TS$ directly could end up with something
like:
"OLD_TSPACE_NAME" in the cache, and "NEW_TS_NAME" in
the table.
You could probably get away with it in circumstances
where you bounce the database to ensure clean cache's
but ... ugh!
Of more concern, if the practice was in place before
you got there, it means they had a system where no-one
got alarmed by this process...That's more of a worry
than the process itself.
Cheers
