It does not. It's your responsibility to include META.yml.
ExtUtils::MakeMaker will generate it for you since EU::MM 6.46 or so.

Correct. If you need modules available to *run* the Makefile.PL,
those need to be included as "configure_requires" in the META file and
recent CPAN/PLUS/minus will ensure they are available before running
Makefile.PL. You can conditionally add them as arguments to EU::MM
like so:
use ExtUtils::MakeMaker;
my %WriteMakeFileArgs = (
# ... normal stuff here
CONFIGURE_REQUIRES => {
'Some::Prereq' => 1.23,
},
);
delete $WriteMakefileArgs{CONFIGURE_REQUIRES}
unless eval { ExtUtils::MakeMaker->VERSION(6.52) };
WriteMakefile(%WriteMakefileArgs);
That will let you add it to configure_requires in META when you build
the distribution, but not breaks things for end-users trying to
install your modules.

Recent ExtUtils::MakeMaker supports BUILD_REQUIRES, with the same
caveats as CONFIGURE_REQUIRES.
