I could go either way. If roster views result in filtering of your
outbound presence then they are essentially a replacement for (some of)
what's now in privacy lists. I like that idea a lot because I don't like
privacy lists. :)

I think that either both versioning and views belong in rfc3921bis or
neither does. The syntax of what's currently in XEP-0237 (using an
attribute to indicate the version number) makes it difficult to split it
out into a XEP, but I suppose that could be overcome.
