GNOME 45 update will break all extensions

There's an open OBS request to update GNOME shell to 45.rc [1]. This update will break every existing GNOME extension [2,3]. As one of the pitiable individuals who have volunteered to co-maintain a few GNOME extensions in the past, I'd like to suggest that this update be postponed at least a few weeks. (No, not every extension maintainer follows GNOME beta releases). I'm particularly surprised that this updated is pushed to Factory while this is still in RC stage upstream. Is it really necessary to rush this breaking change in this way?
