Do the CIP-9 Updatable Parameters require 5/7 signing keys too? I heard only 4/7 and of course no hardfork. Is this true? Any reference (i'm digging but can't find)? Thanks!

Right now it's IOG. Eventually we will be able to vote on changes.

The parameters are controlled by IOG currently. There are a number of keys that govern update proposals. Update proposals are special certificates posted to the chain that can change the parameters. Each update proposal is required to have 5 signatures in order to become active. These signatures have to be in place 1.5 days before the end of the epoch in order for them to become active at the next epoch.

If you do a ledger state dump using cardano-cli, you can view the parameter change proposals and how many signatures they have.
