Yes, it's still missing.  The main problem is conceptual, not physical
-- some CVS commands allow you to specify -r and -D at the same time to
specify a date on a branch, but that doesn't work with diff since it
takes two revisions and there's no way to know how to distribute the
options between them.  It would be nice if the way to specify a tag/date
combination were consistent for all the subcommands, but making
everything work in an upward-compatible fashion, particularly in client/
server mode with a mixture of old and new clients and old and new
servers, would be somewhat tricky.
