I’ve found with my own proposals you really have to play the role of “proposal champion” yourself.
Hi, Ashley. I’m not sure I understand you correctly. FWIW, I have just 2 (two) proposals here on WICG for now.
(Edit: in a private conversation, Ashley has clarified that he thought he “saw the term ‘champion’ used somewhere else in a spec context” and meant that the proposal author himself is who is responsible to “promote” the proposal; so the unclear ambiguous term ‘champion’ is apparently just accidentally used inappropriately.)
best thing you can do to further your own proposal is draft the spec
It does not make sense to write a full-fledged spec (though I’m open in general to do this once the basic idea is accepted) if its horizons are unclear and could easily be clarified on a just-an-idea stage.
(BTW, we’ve already seen what happens when someone writes a spec after being encouraged by a WG member, and then no WG members give attention to the spec.)
I absolutely don’t expect that someone would write a spec for the feature I’ve proposed. What would be enough is just a short explicit yes/no/why opinion by a CSSWG member.
P.S. Please consider using the private-message feature (or the contact form on my site) to send off-topic comments, so that the relevant information didn’t get lost among irrelevant text. Thanks.
