I must say that I find these "XY Problem" shaming characterisations
somewhat disquieting.

Stackoverflow etc. seem to deal with it well by various responders
respecting the original question (the "OP").

Yes, I agree, sometimes the problem is "XY" and it is helpful to
the OP to suggest, gently, alternate, simpler ways to do what they
ultimately are attempting to achieve, if you know what that is.

But often it is also the case that the OP has thought about it and
has asked a specific question and just needs an answer to that, not
some lecture from others about why their approach may be inferior.

In the case of the second example at https://mywiki.wooledge.org/XyProblem,
just saying "rsync", "next" is highly rude. Why not give a complete
rsync command line etc. This just stinks of arrogance. Will rsync
even cope with a corrupted file?
