Even if it could - it would be very confusing and no guidance is provided to implementations for how to support a vCard object being in multiple time zones.

In addition, the property should drop the language about "you shouldn't use UTC offset".
In practice that may be quite useful ("is it the middle of the night in london right now?") and avoids all the complexity of full timezone support.
In PortableContacts we chose to ONLY allow utcOffset and and in microformats we only allow UTC offsets for datetime properties - so this is an interop issue.
It may be ok to leave in a warning, saying something like: "of course, this may not be perfectly accurate since differences in when/whether daylight saving time is observed may cause it to be off a bit" (editorial discretion accepted).
