Deprecation of alternate text in hyperlinks

Version 1.50 of Pod::Parser adds a check and message indicating that 
L<text|hyperlink> is deprecated.  This is based on the following 
sentences in perlpodspec, which has been there since its inception in 2001:

"Authors wanting to link to a particular (absolute) URL, must do so
only with "LE<lt>scheme:...>" codes (like
LE<lt>http://www.perl.org>), and must not attempt "LE<lt>Some Site
Name|scheme:...>" codes.  This restriction avoids many problems
in parsing and rendering LE<lt>...> codes."

Elsewhere in the document, it says that the handler should handle these, 
as in the example

  L<Perl.org|http://www.perl.org/>

The new Pod:Parser has just been installed in blead, and about 10 pods 
run afoul of this new check, including things like

L<[email protected]|mailto:[email protected]>

My question is should there really be a message for this kind of use, 
and if so, should it extend to mailto: links?
