If the "caution" you suggest is operationally equivalent to
discouraging even miniscule improvements, is it any wonder that
progress is glacial?

The gdbstub prototype was constructed for two reasons: to demonstrate
utrace usage now, and in the future to be incrementally useful (over
ptrace, by moving into fast kernel-space operations like
multithreading control, gdb-tracepoint support, other stuff).  #1 is
about done.  With respect to #2, we can certainly commit to ongoing
work on improvements, provided the community shows interest and
goodwill.
