See below.

I understand that. I don't think the community does, but they can be made 
understand it. How much we can have in terms of regression is a subjective 
decision, and one we will have to look into when we're closer to the release.

This is what answers the "now" part. The changes I'm making, like the QRegExp 
one and these deprecation settings, are changing the API that we expose to 
users. As such, I understand that they need to be done, ready and tested by 
the beta release.

Because of that, the QRegExp change could not be postponed. Hence, even though 
fixing them might be low-hanging fruit, they are nevertheless necessary.

Again, because having a proper API that we won't change much afterwards is the 
point of the beta.

If we can't have that, then we don't have a beta. We have a second alpha.
