The name "test" in the title of those is rather misleading. The vast 
majority of their "tests" are not checking any sort of conformance but 
simple feature detection (clearly 2-5 tests per feature, and no 
possibility to check rendering or anything else that can't be covered by 
DOM/javascript isn't going to be any sort of conformance test).

It is very unclear what the advantage of such a test is over a manually 
curated list of which features a browser supports; the latter has the 
benefit that it can account for QoI issues.

The area where contributions are most valuable is actually writing 
tests; I would guesstimate that there are around three orders of 
magnitude more useful work to be done making tests than making tooling 
around tests; this doesn't mean that tooling isn't important but that we 
are chronically short of high quality cross-browser tests for many areas 
of the platform.

If you are going to write tests, please submit them to the relevant W3C 
working group. There is no advantage to anyone of developing an 
independent silo of tests here.
