Thanks for the bug report and the analysis.
As libparse-cpan-meta-perl still exists in oldstable, I'd rather keep
a Breaks/Replaces relationship.

Ack, Parse::CPAN::Meta was merged into libcpan-meta-perl.
And I wanted to be cautious and Breaks/Replaces it with the current
version, even if the separate package had a lower one.
(Which I got wrong BTW, because libcpan-meta-perl 2.150010-1 ships
Parse::CPAN::Meta
2.150010; the 1.4420 seems to come from an older entry in Changes.)
I see two possibilities:
- lower the version in the Replaces/Breaks to <= 1.4414-1, as that's
the last separateky packaged version un Debian; not as
"theoretically clean" as breaking the "real" version but should be
safe within the Debian universe and allows us to fix this now;
- wait a couple of weeks: when perl 5.26 enters unstable this
problems fixes itself; but then the version in Breaks/Replaces and
Provides is still arbitrary/wrong.
I tend to prefer the first solution but I'm happy to hear about
others.
For convenience, here's the diff which I just pushed to the git repo
on Alioth (with a slightly different version to also catch
theoretical 1.4414-1+localsomething versions):
