Maybe you should ask on gdb@.

I personally have never used tracepoints or IPA.  However, I'm not
exactly in the target audience, either, since most of my debugging is on
gdb itself.

Something I found out relatively recently is that agent expressions are
useful for letting gdbserver evaluate (some) breakpoint conditions.
This happens automatically, when possible, and greatly improves
performance.

So, while I don't really mind either way about tracepoints, if we do
remove these we should be careful to keep this part.
