The counters, the phase hooks in idle() and the "health" command are now behind HEALTH, set from the command line with HEALTH=1. Without it the hooks are empty macros and the command does not exist, so a default build carries none of it: on SWTGW218AS that is 1065 bytes of bank 2, 101 of the common segment and 28 of xdata, plus seven banked calls per main-loop pass. It is a developer's tool. Reading the dump takes knowing the main loop, and a user who needs it for a report can build with the flag on, which is how the kernel treats its lock and latency instrumentation as well.
