I agree, for what it is worth, with, almost, all of the above! I have grinded up some frames along the way, even the last one. Then I bought a fresh one, just a few bucks, to keep it standard....... for a few weeks and then I removed some parts of it. What I am trying to say is, do whatever pleases you and when, or if, you want to return to standard get yourself another one, there are enough lying around.
Let's get the grinder out!
cheers.
