I think the first question is what the default behavior of `revert-buffer' should be -- after we decide that, we can decide what special prefix arg is used to access the non-default behavior.
Stefan proposed that the new default be to *not* reset modes, and that C-u could be reassigned to mean "and reset the modes". Here is what he said:

To consider Stefan's proposal, we'd have to first decide that `revert-buffer' will no longer reset modes by default. I had thought you were opposed to that change, on compatibility grounds. But maybe you just meant that revert-buffer's `preserve-modes' argument should retain its current meaning when called non-interactively from Lisp, but that it would be okay for interactive `revert-buffer' to stop resetting modes by default? In other words, the default interactive behavior could be changed to be the opposite of the default non-interactive behavior.
Was that what you were saying?
Regarding Stefan's proposal: I don't know how often people depend on the current C-u behavior of reverting from auto-save file. But if we're changing the interactive default to not reset modes, then I think a special prefix -- different from C-u -- to access the old reset-modes behavior would be fine, partly because it would be rarely used! Also, I presume we would have a new customizeable variable `revert-buffer-reset-modes' (defaulting to nil) that people who have a permanent preference could set.
Best regards,
