Geist on Nostr: A miner activated soft fork can create a new transaction type without everyone else ...

A miner activated soft fork can create a new transaction type without everyone else patching their nodes? Can't we just try normal merged mining for a while and not jump to a consensus change for side chains? If miners want to run side chains can't they just run a node for those, is that a bigger ask than pushing a masf? If side chains pick up adoption then drive chains will be an upgrade that saves space on chain so the upgrade will be obvious, and if they don't then we haven't lost anything.
