That's a little bit disingenuous, methinks.  Support for the
"deprecated and experimental extension" -- RFC 1644 -- was dropped a
number of years ago.  (Longer ago than I can easily recall.)  The
implict open/close mechanism is orthogonal to the long-gone support
for RFC 1644.  There may be good reasons to remove it anyway, but
please don't claim that the status of RFC 1644 has anyting to do with
it.
