I agree we don't want to provide this to users to *work around*
issues. But maybe we want something like this to *debug* issues?

We have a plethora of unsafe/debug module parameters mainly because
they're convenient and take effect from the beginning of the probe. If
there was anything comparable for debugfs, I'd be all in.

Should we have this in debugfs instead?

Cc: Lyude for insights too.

BR,
