I'd legit rather the software develop and occasionally spaff it up and break the server for a few hours every once in a while rather than the non-moving 5 year plans of Lemmy development.
Also, usually piefed.social is the only instance that gets hit with this as, being the flagship server - it takes the brunt of more 'experimental' features. Most other servers don't upgrade to the latest iteration until they're sure it's not going to break them.
