I appreciate the detailed response! And I apologise for taking up your time 
For sure - but there’s also many scripts that are being actively updated / have already been updated, and would have benefited from having a couple of days on preview to save some stress and to avoid users having their experience messed up.
Fair. I think my issue was it was almost too much notice, as a future thing that could happen in months and months I (and I’m sure others) didn’t really prepare in the same way as if there’d been a post saying “in three days time, this will break if you don’t have an update ready”. But yes, I do appreciate you having provided that original post.
I don’t envy your situation 
I do wish though very occasional updates could be provided even if just to say that e.g. it’s still under consideration, or that it’ll likely take a year or two, etc. It would make it seem less like an “abandon and ignore all feedback” situation from WK…
I do understand your point of view. I think the issue is that there’s quite a lot of people using scripts (a much higher percentage than the average website) and a large community has been created around it, with many incredible scripts. This can then be used to argue (by other users - WK doesn’t seem to have taken a stance on it) that features you can get with scripts don’t need to be implemented into WK even as an option (e.g. dark mode, heatmap, double-check, pitch info, custom items, etc.). Which is an issue, as scripts are inherently unstable if support isn’t provided (which as you rightly say is difficult).
It’s an impossible situation - I just wish a better middle ground could be found. I do like WK a lot, but it can feel a lot like “big corporation that doesn’t listen to its users” sometimes, when I originally got the impression it was more than that.
In any case, congrats on cleaning up the code so much - as a dev myself I know it’s always very satisfying to get old code cleaned up and improved (oh and also your gradual move to more CSS variables is greatly appreciated, it makes dark mode styles a bit easier to maintain). And I do appreciate the time you take to respond here on the forum, that is already a step up from most companies
