A config option to disable the PneumatiCraft village house from spawning would be appreciated. This is especially useful for progression packs, where the villager and village house could be used to skip progression/get access to pneumaticraft earlier than wanted.

Yeah, that's reasonable. I'll get that into the next release.

Build 71 from https://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized-1.15/ has this functionality added, if you'd like to test it out. See the Villages section in config/pneumaticcraft-common.toml.

It's possible to disable generation of houses, and disable the trades a Pressure Mechanic offers (or limit the trades to only the PCB Blueprint). Switching off Pressure Mechanic villagers entirely is not an option (controlling registration via config is a no-no), but the changes I've added should prevent any issues with progression.

Note also the config settings should be applied before worldgen happens; any houses or villagers which are generated beforehand won't (can't) be affected by these config settings.

Added in 1.5.0 release
