CSS is Complex. We can do better.

Ok, thread time.

CSS is unnecessarily complex. And we can do better.

There have been side conversations here and there, but I want to consolidate the information and opinions here. This will be a running thread, and I'll add to it as new things crop up.

Huawei Matebook x Pro PCI-Express 2 lane bandwidth limitations with eGPU

"In short, with current TB3 overheads, 2 lanes is enough to transfer data to the GPU. If you use a display connected to the external GPU, you'll see almost zero performance difference. If you want to use the internal display of your laptop, 2 lanes is not enough, and you'll need 4 lanes to shuffle the DisplayPort data back."

	// differential code loading.

	// This is distinct from things like https://www.npmjs.com/package/ua-parser-js
	// which distinguish between different branded browsers that use the same rendering
	// engine. That sort of distinction is maybe useful for analytics purposes, but
	// for differential code loading it is overcomplicated.

	// $ReadOnly doesn't recursively apply invariance to nested object types, and there
	// doesn't seem to be any way to do this besides making a separate copy of obj A
	// that is invariant. I still want the variant A around in case I want to mutate it
	// in certain contexts.

	// It would be nice to have some way to use an object as if it's fully, deeply
	// invariant without needing to declare a separate variant and invariant type for it.
