Going by modern nomenclature, Frasier was a “reboot” of Cheers

I'm not sure what you're getting at here. Frasier was a spin-off.

Family Matters was a “reboot” of Perfect Strangers

This makes even less sense. Family Matters and Perfect Strangers aired concurrently. This is like saying Angel the series was a reboot of Buffy The Vampire Slayer.
