I'll answer b)

First, keep in mind that WhatsApp patches are highly specific to their
application and not optimal everywhere else. I'm not quite sure which timer
wheel patch you are referring to but I suspect it's the "multiple wheels"
patch. OTP implemented multiple timer wheels in 18.0 along with numerous
other optimizations.
