You've written to the MediaWiki technical list, which probably is not the right place for this discussion.
Sure it is. It is a question to the System administrators by the community (or parts of it). Discussing it in the community itself won't help answering the question.
foundation-l might be a bit better than wikipedia-l, but still it is a very concrete and legitimate question: "Will the system administrators change the default skin for a wiki, provided there is an consensus by the wiki community?"
A simple "Yes" or "No" would suffice.
(I'd argue that changing the skin to vector is a strategic decision by WMF and cannot be overruled by local communities - but that's something a system administrator has to decide.)
