That said, after taking apart a Mk4, I would never go back to a Mk2.
I've handled MkIIs that had the receiver/barrel assembly wobbling around slightly on top of the frame, presumably due to wearing down the mating surfaces by compulsively breaking down and cleaning every damned day. This probably had only a modest effect on the accuracy, since the sights, receiver and barrel are still one solid unit. If I had to bet, I'd wager only a Ransom Rest or a VERY good bullseye shooter could prove the difference. Still, not a quality I'd want in my gun.
It's not actually necessary to detach the receiver from the frame to clean a Mk 2 or 3. Once that thing in the back is removed, the bolt just slides out.
That's true, but once you pull out the mainspring assembly, "in for a penny, in for a pound" is my motto. Or more like "in for a pound, in for a penny," since the replacement of the mainspring assembly is usually the worst part. Once you've pulled that, you're committed.
I go beyond the boresnake or home-made patch puller only rarely, so by then removing the receiver for unfettered access to all the gunk down there is nice to have. Also, my favorite step in the process is whacking the back of the receiver with a softwood 2x4 to pop it off! I suppose fancy people use a rubber mallet.
Since I wrote the above, I found a post elsewhere saying that the loose fit of the frame/receiver is probably more due to tolerances in the original stamping and welding together of the halves of the frame than wear. In any case, it said that VERY gradual clamping of the sides of the frame in a vice could be used to restore the fit to snugness. Sounds plausible, but I'm glad I don't need to do that to any of mine.
