There is this risk indeed. But considering the two demographics:
1. People who use ControlMaster in ~/.ssh/config
2. People who have very old ssh clients
I think that 2 is probably smaller than 1, especially if ControlMaster
is such a momentous thing. So i think the risk is worth taking.
Especially because an error for people in 2. is easier to recognize,
understand and report than an inexplicable Emacs hang. And Eglot is a
:core ELPA package, so bugfixes can be expedited.
