No problem, being critical is easy.

'emacs -Q' won't let you reproduce this, because (I think) it won't load 
~/.emacs.d/elpa/archives/melpa/archive-contents during `package-initilize'.

I've pulled the latest changes, re-bootstrapped Emacs, removed 
~/.emacs.d/elpa/archives, but after restarting Emacs, the problem persists.

Certainly. But `g' is a common keybinding.

My point was different: in VC-Dir, when [waiting...] disappears from the 
mode-line, I can be sure that the list is not outdated.

Not so with your proposal. "The list is outdated" - this information 
won't be apparent from the interface.

Anyway, merging the items on the fly would solve that.

Good.

Indeed, that should be rare. I don't have a scarier scenario to offer 
right now, so maybe we can ignore this downside (but preferably handle 
the possibility with care; and not move the "to install" mark to the 
now-incompatible package).
