I'm not sure it's a minority.  How about if you come up with a list of
specific commands that launch subprocesses which don't need a PTY?

But assuming you are right, you intend to audit all the places where
we start a process and switch their :connection-type to nil if needed?
Or change the default value of process-connection-type?
