You are devolving Patchmanager with this plan.
This is how it has worked historically (PM2.x), which resulted in bad, bad times at times.
I recommend looking into src/preload/src/preloadpatchmanager.c and try to understand what this does and why, and its connection to the perceived shortcoming of the current implementation.
You seem to have so far missed to this core piece of Patchmanager functionality.
If you want to go back in time though, there is a fork called “pm2-forever” in this repo which as far as I understand is dedicated to the old ways.
