Yeah, someone with a bit of spare time could make it happen:

  https://lkml.kernel.org/r/20250703141800.GX1613200@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

It would be:

 - convert all the accounting sites to tracepoints
 - write modules that connect to relevant tracepoints to provide the
   'legacy' interface
 - convince world+dog to not auto-load above modules
 - have beer and wait for people to complain about something :-)

I'm sure there's 'interesting' details glossed over, but I *think* it
should be doable.
