People who install Tramp's GNU ELPA package.

This command is triggered by error report(s) on the Tramp ML. Scenario:

- Run an older Emacs version, say 27.2.
- Load tramp.el (this happens often, implicitly)
- Install Tramp 2.5.0.3 from GNU ELPA

There is a compilation error, because the already loaded tramp-compat.el
does not fit the expectations of Tramp 2.5.0.3.

D'accord.
