Just to be sure I get everything right.

The idea is to try to have www/qt5-webengine fixed before the expiration 
time, saving with it a bunch of innocent ports depending on it, correct?

P.S. I want to make clear I have no objection about the removal of 
python 2.7 and I'm really appalled by the situation with chrome build 
system (*). I'm just letting the little worried user inside me express 
his worries. I'd like to understand how we can reach the objective 
without killing a bunch of perfectly working, supported and useful 
software that is now being deprecated due to depending on 
chrmoium/webengine. So I only ask a few questions to get the picture.

If I sound rude please pardon me, I really don't mean to be rude or 
demanding!

Is there some ETA on these? Is it realistically possible for these to be 
ready before the end of June?

Is the deadline amendable if the plan does not unfold as expected? Or 
are we really going to drop kde and a bunch of other working software to 
stand out ground?



(*) I'm also really appalled by the fact that in the last few years 
almost any software started having the need to include a fully fledged 
html5/js engine but this is another story.
