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.)
