Browser Support • Re: Why is Pale Moon so slow?

I will word this as politely as I can from somebody who has followed the development of Pale Moon and UXP for many years.

other factors that Google have little to no control at all such as how fast JavaScript and CSS change/adapt. All programming languages change and add new features over time.

They are in large part responsible for pushing many of these changes through WHATWG and their contributions to the two languages you mentioned; the impact of V8 on JS development, for example, is not to be underestimated. Google's vertical web integration is not coincidental. While yes, browsers should aim for some compatibility (in my eyes, Pale Moon has plenty), bending to the whims of a corporation that has zero regard for the end user with the standards they push is not the ideal way to go about it. This includes haphazardly including support for draft standards.

Off-topic: I suspect you have already come to the conclusion that this is not what most of the userbase desires, going by your and Basilisk-Dev's recent all-but-split. Bringing me to my next point...

because nobody else is working on performance.

I suspect this is an attempted jab at UXP's development seeing as you and Basilisk-Dev have recently, without zero forewarning or willingness to cooperate with upstream development, branched off into your own thing. It's quite a light jab, considering it's quickly disproven by checking the UXP repo's commit and issue history. athenian and Moonchild (and yes, you and Basilisk), have all been working toward improving performance. Passive-aggressive jabs such as this are quite immature when the reality is different. I suppose it's easier to just push cooperation to the side and splinter a development team.

And finally..

Please don't make assumptions for me, what my beliefs and views are, or about me.

Perhaps if you communicated with the rest of the project, instead of vaguely masking your discontent behind sentence fragments such as "I agree", this wouldn't be a mess in the first place. The beliefs you are stating are clear from your splintering, so I'm not sure why you are up in arms regarding "assumptions" being made.
