I'm so sorry for the late reply! Just to let you know what's going on:
As Carlo wrote in the PR, the icon stuff is on pause because it's a burning hot topic atm. and there's many things to consider.
More info about the heated discussion can be found here, but I can try to boil it down for you:
- Gnome upstream wants us to ship their new icons
- Not to belittle Gnomes work, but we think the suru icons looks better
- Upstream icons are optimized to scale best at 32px. The dock in Ubuntu is 48px
- We would like to ship only suru icons but Snaps will keep their original cross distro icon
- If we want suru icons, it will be a HUGE task
- We are not icon designers - we simply tried to pick up the pieces to move the project along
- We (the Yaru team) do not make the final call, Canonical will
So in short, we might go all suru or full upstream or we might do a mix - we don't know atm. Anyway, the icon work is paused for now. It was bad timing of me, to reach out to you - sorry!
