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.
