Re: adding META.yml "provides" with ExtUtils::MakeMaker

Two notes:

- yes, things used by Makefile.PL itself go into CONFIGURE_REQUIRES,
but everyone has Module::Metadata, as it is in core (it was split off
from Module::Build a long time ago, and has remained in core even
after MB left).
- Dist::Zilla is capable of generating distributions for any perl
version -- quite a number of toolchainy modules are built with
Dist::Zilla and maintain compatibility with 5.6 (and occasionally even
lower, but it's so hard to test these days that 5.6 has become the
defacto minimum for even the most die-hard gerontophiles).
Dist::Zilla::Plugin::MetaProvides::Package is the plugin you want.
