In any case I have been looking around and this is not really critical
cause only few active/extended packages will be directly affected for
this now. If there are some inactive-old-unmaintained package you know
will be affected and it is probably unmaintained, then probably we can
contact the author, make a pull request or in the best case, recommend
other with same functionality, but more active-maintained-supported.

Magit counsel-swiper and Helm, for example, I am pretty sure they will
receive the update immediately once we publish the recommended way to do
so without breaking backward compatibility.
