If you wanted to take that type of approach to other prefixed features, I doubt I would object in most cases. As I understand the policy, it's just asking for a reasonable effort to gather data relative to what we know about the feature. Perhaps you and other readers of the policy see it as demanding an unreasonable level of work, but I don't think it does.

But I disagree that we have an "obligation" to follow a Working Group's request to remove something, either in general or by virtue of participating in the Working Group. Joining a Working Group carries no obligation to add or remove support for anything; W3C, IETF, ECMA and other bodies are pretty clear on this. Maybe it's a good thing to do to listen to requests from the Working Group, but it's certainly not an obligation.

Yeah, "obligation" is probably too loaded a word. Here's some updated text:
* Standards citizenship. Many W3C working groups, including the CSS
working group, request that implementors remove support for vendor
prefixed features once the specifications of the features reach a
certain level of maturity, typically Candidate Recommendation. To be
good citizens of these standards bodies, we should make an effort to
remove vendor prefixes, even if doing so would incur a larger
compatibility cost than we would otherwise prefer.
