Yes. Progress is good, though I am actually considering making the changes just for Krita. That would kind of fork komain for krita, but keeping all the applications running properly is just way too much work for me, and for very little return.

I haven't seen a lot of comments about performance, just one or two. But performance always should be better, and images are growing all the time... I did measure the impact of lcms2 on Windows, and according to vtune, it's about 90% of cpu time when painting on a 10k x 10k canvas with a big brush on a 16 bit integer image.
I haven't measured what happens when moving the color correction to a shader yet, but that is pretty similar to what the ocio docker does.

I wouldn't actually care much about backward compatibility, as long as we can convert vector layers from odg to svg on loading, we should be fine.

For the text tool, I rather think that the current approach really is broken by design. The ODT format doesn't offer the kind of typographic control that our users need, while on the other hand, it offers a bunch of things nobody needs, down to integration with bibliography databases.

Flake already supports svg to a surprising extent though.

Yes... And that probably needs to be done anyway after the MVC merge since the way I see it going now we'll manage shortcuts ourselves, separate from KDE.
