It looks like this is a concious decision by upstream, it's even documented
in perlvar(1):

    The array @INC contains the list of places that the "do EXPR",
    "require", or "use" constructs look for their library files.  It
    initially consists of the arguments to any -I command-line switches,
    followed by the default Perl library, probably /usr/local/lib/perl,
    followed by ".", to represent the current directory.  ("." will not be
    appended if taint checks are enabled, either by "-T" or by "-t".)
