Separating the Charter from the timeline sounds reasonable to me. We'll still need to figure out what the incentives are for keeping the timeline up to date and accurate though.

Also, I am not sure ETAs and priorities are the same thing. It is not a rare situation to have multiple members or even the majority of the WG agree that something is high priority, and many people spend plenty of energy advancing the spec, yet nobody commits to making (or to sharing) tests. In the absence of tests, the ETA is still infinity. Is the priority low though? You could say so, since arguably, people should actually commit resources to testing when something is high priority, but by that metric nothing is high priority, making it a pretty useless concept.

Sure, but we cannot have a realistic ETA for specs unless we figure out the resource assignment. so the member priorities issue is a dependency for the W3C process issue, and that's what makes it broken.

And when I say that we need to figure out the resource assignment, I am not speaking fine grained projections. Even answers to very basic questions like "will any member company of this working group submit tests for this specification within the next 3 years", or "will anyone review these tests that have been submitted a year ago" tend to remain unanswered (not always, but often enough).

Totally. I think the testing effort is probably suffering from death (or at least serious damage) by a thousand paper cuts, and we will need to address many issues before we start seeing the results we want. The CSSWG, taking lessons from WebPlatformTests, is currently changing its test submission and reviewal process to lower the friction, and that should help.

Among many other things, there's also probably an issue of social prestige difference. If you do spec works, you get to attend all these nice(?) meetings and fly around the world. If you do test work, the action's over here on github. If you lead spec work, you get to put your name at the top of a fancy document the whole world will look at. For tests, authorship can be found in commit logs... I am certainly not claiming that prestige is the main reason people join a working group or do spec work, but I would not be surprised if it did play a role in tilting the balance.
