Review Comment:
Thanks!
I agree this code was deliberate & nice. I hope we don't parse those names
though.
If there is a better solution to agg reverse causing failures
(https://github.com/apache/datafusion/pull/16625#discussion_r2176919070), let
me know. I can also drop this fix, I don't like it too.
Alternatively to the fix, I can block reversing for beneficial functions and
thus hide the problem for now. Would it be preferred for this PR?
