BPX ptrace...Does that mean performance is not an issue in that case?

That seems like a logical conclusion.

When the system is running in a privileged state, just about the only safe way to give control to non-privileged work running as an exit or extention under that same task is via SYNCH. That is not going to perform well. Returning to the user in their state is a different case.

Oh - hmm - it would be nice to have a non-supervisor-state
thingy that did this - similar to what is available via PTRACE.

But - "would be nice" doesn't make for a good business case :-)
