Your case is surely valid, but sounds a bit niche to me. It shouldn't be 
too hard to evaluate this, though:

(with-eval-after-load 'tramp
  (trace-package "tramp-"))

And the current patch makes it easier.

Considering elp-instrument-package does not do that, I think we should 
limit the scope of the currently discussed patch, and trace only already 
loaded functions.

If we do what you suggest, it should be a new discussion, and it should 
improve elp-instrument-package as well.
