Make no mistake: it's an awful crutch (I think that Stefan would likely
agree that it's only justification is that it is hard to come up with
something better) and should at some point of time be the default.

I don't think I've written code that would mind that switch: relying on
dynamical binding, particularly without properly declaring the involved
variables, is just so awkward.  Nevertheless, there likely _will_ be
non-negligible amounts of code around that do mind.

I don't think anybody is happy about them.  Come up with a better
migration mechanism, and I guess you'll have people's attention.

At least it is a noticeable clue of the "if this module does not work on
your version of Emacs, this will likely be the reason" kind.
