imo, no definitely not
“there should be/are governance cycles” is an offchain understanding/agreement not embedded in code
there is no mechanism for binding all delegates or other ecosystem participants into this offchain understanding/agreement
even if there were such a method, there is no practical way to enforce that understanding/agreement
imo ZkSync should not fall prey to the same ‘let’s make up a bunch of offchain rules with no documentation/enforcement mechanism’ trend that so many other DAOs have–let’s stick to the chain
