no deprecation warning for L<section>

I was reading podspec, and saw this

  Previous versions of perlpod allowed for a "L<section>" syntax (as in 
"L<Object Attributes>"), which was not easily distinguishable from 
"L<name>" syntax and for "L<"section">" which was only slightly less 
ambiguous.  This syntax is no longer in the specification, and has been 
replaced by the "L</section>" syntax (where the slash was formerly 
optional).  Pod parsers should tolerate the "L<"section">" syntax, for a 
while at least.  The suggested heuristic for distinguishing "L<section>" 
from "L<name>" is that if it contains any whitespace, it's a section. 
Pod processors should warn about this being deprecated syntax.

I notice that perldoc does not warn on this being deprecated.  Is this 
by design?
