MANIFEST.SKIP vs. libscan()

Wouldn't it make sense that if there is a MANIFEST.SKIP file that it 
would be honored by libscan() so that files that are to be skipped when 
validating the MANIFEST are also not included in the generated makefile 
rules (e.g., in the definitions of TO_INST_PM, PM_TO_BLIB) or am I 
misunderstanding its purpose?  (I know the primary purpose for 
MAKEFILE.SKIP is in regards to validating the MANIFEST, but it seems to 
be a logical extrapolation that it should be honored when building the 
Makefile rules too.)

An example is temporary vim files (e.g., *.swp).  If present, they're 
found by libscan() and included in TO_INST_PM.

The (only?) solution I've come up with is creating my own MY::libscan in 
Makefile.PL that filters the results from the default libscan 
(ExtUtils::MM_any::libscan()) using the regexp's in MAKEFILE.SKIP; like so:

# 
=============================================================================

my $skip;

# Exclude any files matching patterns in the MANIFEST.SKIP file from being
# included in rules in the generated Makefile.
#
sub MY::libscan
{
     unless (defined $skip) {
          # Newer versions of ExtUtils define maniskip(); older versions 
(like
          # what we're using now) define _maniskip() -- use whatever is
          # present, preferring the newer, "public", name.
          #
          if      (defined(&ExtUtils::Manifest::maniskip )) {
               $skip = ExtUtils::Manifest::maniskip();
          } elsif (defined(&ExtUtils::Manifest::_maniskip)) {
               $skip = ExtUtils::Manifest::_maniskip();
          } else {
               $skip = undef;
          }
     }

     my $path = ExtUtils::MM_Any::libscan(@_);

     return ($skip && $skip->($path)) ? '' : $path;
}

# 
=============================================================================


Note that we're using an old version:

# It was generated automatically by MakeMaker version
# 6.17 (Revision: 1.133)

Although I looked at the latest version (6.50), and didn't see anything 
new that would honor the MANIFEST.SKIP in the building of the Makefile; 
apologies if I missed it.
