Consider whether your fixation on getting your framework adopted into Perl core is based on ego.

That would be quite some egos here.

Damian Conway, who created several OO frameworks which are available on CPAN, wrote about disadvantages shared by all OO frameworks which are not in the core.

Also, I trust the Perl porters and the Perl Steering Committee that they won't accept it into the core if they wouldn't think it fits.
