Yes, there are risks, but those risks could be managed with appropriate
effort. Major players could publicly commit to a set of ground rules vis
a vis what categories of changes are and are not acceptable.

Maybe at some point there could even be something that resembles project
management for the Bitcoin protocol.

Why not schedule protocol upgrades every two years for the foreseeable
future?

Spend one year achieving broad consensus regarding what changes to make
in the next upgrade, then spend one year in feature freeze (all future
proposals postponed for the next cycle) then execute the upgrade.

The top priority should be fixing bugs that make specifying and
re-implementing the protocol nearly impossible. Those kinds of changes
should have little difficulty achieving near-unanimous consensus.

There shouldn't be any problems separating obviously-needed changes from
the ones that let third parties blacklist coins, or a majority of miners
vote to confiscate block rewards from minority, tamper with the issuance
schedule, etc.
