This is not a fetchmail issue and this whole discussion is unrelated to
fetchmail. If you are really interested in improving procmail's error
behaviour, you should move this to the procmail-list.

As a sidenote: I doubt procmail is so bad, but you never know. Anyway, I used
maildrop for quite a while. Main reason was its non-obfuscating filter
language, but it also has a proper error handling. And I never needed anything
like formail to use it as MDA.

By whom? Certainly not by any fetchmail maintainer.
