Really? The spec might maybe be hard? Perhaps? I don't know for sure.

But there is a long long long legacy of CSS Acid Tests that have been very well established & expected, that should guide most implementations to success.

I forget what it's called but a bunch of the major browsers get together each year & find a couple things to agree to focus on & make happen each year. Trying to just play catchup & go through the years catching up seems semi intuitive a path to getting to modern. I agree that maybe not all these specs have gotten great test suites set up, but I feel like CSS in general realized this was a problem we'll over a decade ago & upped their game. Maybe the situation has decayed since, I dont K ke, but would love more idea of where we lie atm.

The old Web Standards Compliance Acid Tests aren't used by implementors.

Do you have any references or links or whatnot to support this? I thought css group was still big into testing. They're no longer called acid tests but I thought it was all still alive & well.

They are, they just don't use the Acid 1, 2, or 3 tests that you're familiar with. They currently use a manual test suite, which requires humans to look at reference output and compare it to what the rasterizer and compositor are doing.
