Devs can propose rule changes. They can't enforce them. Only full nodes and miners securing the network can enforce rules.
I'm going to call you out on this each and every time you lie about it. Devs cannot enforce rule changes.
of the network is supplied with stripped, non-full data the network no longer enforces full validations. they are automatically trated as scond class(downstream/bridged nodes) or as you call it "compatible"
If you went out for a meal with a group of people and you're all eating together, then everyone else decides to order a dessert, but you don't want to, do you then whine about being treated as a "second class" attendee? Have they "bypassed consensus" for that meal just because you don't want a dessert? Are you going to hold a petty grudge against that one person who proposed having dessert and blame them for everything else you don't approve of for the rest of forever?
Congrats on your -ve trust, by the way. I'm surprised it didn't happen sooner to be honest.
