I am not sure why you think it is "management responded" -- it is all about other people on the team.

Right now, I am responsible for maintaining one of our internal services. If someone tries to rewrite part of it in Clojure without extensive internal discussion first, I'll do all I can to stop it (and I am not "management" at all). And most people on the team will agree with me.

If the original dev would not want to stick around after that, good for them. If they do not care about teammates at all, they would likely be happier working alone anyway.

After all, single-handedly moving to a new technology and then forcing everyone else on the team to support it is impolite and annoying. Clojure is nice, but I don't want to be forced to learn it because the server went down on my shift.

(this is different if the service does not need to be up all the time, or the company is very small. But if you are talking about API endpoint being overloaded, the chances are, neither of this is true)

“single-handedly moving to a new technology and then forcing everyone else on the team to support it is impolite and annoying”

The dev you’re describing has indeed made some bad choices and I wouldn’t want to work with that guy either.

What I had in mind was more along the lines of “check out this thing I made, what do you think?”

Totally ok responses would include: “let’s just bypass the ORM here instead”, “let’s divert 5% of traffic to it and see what happens”, “this stays a prototype until you reach a bus factor of 2”, etc.
