As far as I'm concerned, it's yet another case of the freezer papering
over a problem rather than fixing it properly.

If we're going to introduce new callbacks, we should have the right
semantic from day 1 -and- fix those problems, rather than going to the
same old recursive nonsensical arguments and do things to paper over
problems.
