The reason is probably that it is indeed invalid.  From rfc822:

mailbox		= addr-spec / phrase route-addr
addr-spec	= local-part "@" domain
phrase		= 1*word
word		= atom / quoted-string
atom		= 1*<any CHAR except specials, SPACE and CTLs>
quoted-string	= <"> *(qtext/quoted-pair) <">
route-addr	= "<" [route] addr-spec ">"
...

where 1* means "at least one of".

That is, either you must not use <...> or you need a non-empty phrase.

Actually this grammar looks wrong, because as I read it it would not
allow spaces between words in phrase.  But that's another issue.

BTW: Outlook depends on this, because if you use Cc:
<stable@kernel.org>, it doesn't show anything in the Cc: line---at least
in the default configuration.

So I suggest the following:

---- >8 ----
send-email: rfc822 forbids using <address@domain> without a non-empty "phrase"

Email::Valid does respect this considering such a mailbox specification
invalid.  b06c6bc831cbb9e9eb82fd3ffd5a2b674cd940d0 addressed the issue, but
only if Email::Valid is available.

one of them, would you go to lunch or read the paper?
