completing-read-multiple is not supported by ivy and similar about magit HOT 1 CLOSED

Thanks for a thoughtful message!

Funny enough the last thing I did before going to be was to stumble into some compatibility code for Ivy in one of my packages and wondering how long it would be until I could remove that. And the first programming related thing I did after getting up, was reading your post.

I think Ivy's time has passed. I used it myself for a few years and it deserves a lot of credit for paving the way for the current crop of completion packages. That being said, it does not use Emacs' completion infrastructure and that is a fatal flaw.

Because of that alone, it will not survive for that much longer. The question isn't if it will cease to be framework that other packages will/should accommodate, but when. At this point in time, I personally am willing to preserve existing compatibility kludges but don't intend to merge any new ones.

Users should migrate to Vertico, the new built-in vertical completion setup, or some other package that builds on the built-in completion machinery. Coming from Ivy that should require minimal effort and would result in an improved experience.

By using compatibility code such as found in the issue you linked to, one can avoid making that step for a little longer, and doing that is okay. If you decide you go down that road, then I suggest that you begin by investigating how to best implement that outside of Ivy, as well as, outside all the packages you use, which use completing-read-multiple. The code you linked to, could be a suitable starting point, but its possible that there are other, potentially better, implementations or even extensions floating around. Eventually you should try to get that merged into Ivy itself.
