Even if your poll shows that nobody polled intended to use bare CRs or LFs in
their addresses, would you feel justified in not providing support for them in
your mail handling software?  After all, if you fail to support that part of
the standard, you can't claim that you follow it.  Who knows what somebody
will try to use as an address some day?  For whatever reason?

It sure sounds like interpreting quoted CRs and LFs as other than text (e.g.,
as a line break) is a bad idea, also.
