It does cost something, quite a lot actually, my company (correctly) refused to bow to the pressure to migrate because it would have been too expensive to update our tooling.

And acquiescing meekly to absurd demands is a much worse behavior for a team.

Even worse behavior in a teammate would be trying to browbeat their coworkers into wasting energy on performative nonsense to score social status points.

In a just world anyone who suggested this would be fired immediately.
