The full list of deprecated scheduled-for-removal properties is below.

'-' indicates a dummy value (that only exists not to throw exceptions if referenced by scripts, functions are no-ops), '+' indicates an actual value (functions that do things, non-undefined values).

I think that we probably can safely remove "Spinner creation, injection and removal" and "Toggle checkboxes with shift selection" and "Escape utilities".
We probably can't safely remove the rest. (But, again, I have no data on this and this sucks.)

Cherry picking only a few of them is not an option imho.

They were intended for removal in 1.23 following a more public-engaging deprecation process.

However, both the tracking of usage and the announcing of how to use mw.log.deprecate were delayed.

I announced a bit about mw.log.deprecate in last October:

And only last week did Ori and I start putting the bits in place for tracking mw.track('deprecate') usage on Wikimedia wikis. We're still working on that.

I think once that is in place and we've sent a second reminder to wikimedia and mediawiki mailing lists about them going away soon, we can safely remove them in the next release. It is developer's responsibility to keep scripts up to date.

Wikimedia can do a best effort to keep popular gadgets that are abandoned up to date, but overall we should not cherry-pick speed up or delay removal of features just because of how well or how much they seem to be used.

I don't see this blocking 1.23.0...

Hmm. Okay, so do we just s/1.23/1.24/ in wikibits.js for now, on master and on REL1_23 branch?
