In which case somebody will only implement the protocol and do whatever
they want with the algorithms, and clients will connect to this server
and there will be a significant chance that because of the different
algorithms, the behavior will be different and there will be train wrecks.

We've already seen what happens when people put leap smearing servers on
the public internet, and somebody says "Oh, I got bitten by not having
enough servers last time, so I'll use 4 now" and then the learned that
during the next leap event two of their upstreams offered correct time
while 2 offered smeared time, so "no consensus" on time and off they went.

Different timing algorithms will cause much bigger problems.

NTP is all about a defined impulse response.
