Where is ExtUtils-Install maintained?

Last month I sent this message to the perl5-porters mailing list.  I got 
no replies.  Does anyone on this list have thoughts on this?

#####
Two recently filed RT tickets ...

https://rt.perl.org/Ticket/Display.html?id=121829
https://rt.perl.org/Ticket/Display.html?id=122596

... led me to look for the source code for ExtUtils::Installed and 
ExtUtils::Packlist.  They're part of the ExtUtils-Install distribution 
which is distributed with core.

In the core distro, ExtUtils-Install is found under 'cpan/', which 
suggests that it is *primarily* maintained on CPAN by one or more 
maintainers, and not maintained by P5P.

However, when I go to 
http://search.cpan.org/~bingos/ExtUtils-Install-1.68/, I see that this 
distro's bug tracker is listed as http://rt.perl.org/rt3/ and its 
repository is listed as http://perl5.git.perl.org/perl.git/.  In other 
words, it's maintained in core not on cpan/.

If so, then shouldn't ExtUtils-Install be under 'dist/' rather than 
'cpan/' in the core distribution?

 From pod/perlsource.pod:

dist: "This directory is for dual-life modules where the blead source is
canonical."

I'd like to clarify this before embarking on work on either of the two 
RTs cited above.

Thank you very much.
