Well the blog only seems to have staff posts, so i would assumed they just shelved the idea, that thread you linked is nearly a year old at this point
FWIW, (Which is very little these days! ) - I posted again on the linked thread but I recall the subject was raised again (off public forum) by SU's earlier this year but we need VM to answer/clarify on current "public" status.
Not "shelved" but "work-in-progress" but then I have been on medical leave of (community) absence since June and not actively enquired/participated on SU,Trials or public community forum and recent unfortunate "SU Group membership" events means it appears highly risky to even "speculate", or hint at any positive constructive feedback in case this is interpreted by VM Forum management as "conflict-of-interest" and/or non compliance with SU ToR's/confidentiality. Somewhat paranoid outlook on my part perhaps but VM make the rules even if they are not always consistent with their own interpretation! "The road to hell is paved with good intentions"!
