So the very ROUGH numbers I have are that ~3900 out of 35,000 modules on CPAN use Module::Install. That's ~11% of CPAN. I'm not optimistic even Karen could get patched or adopt that many modules. This would probably be with us for some time. I got this by putting all of minicpan into a git repo and I know there are a few dupes. https://github.com/toddr/minicpan_grep

After talking with toolchain, the below idea has been floated. It would allow us to ship ONLY this one file and not M::I with Perl. We could add docs, warnings, etc. to make it clear this is a shim ONLY for working around Module::Install's incompatibility with . not being in @INC.

File: lib/inc/Module/Install.pm
package Fake::inc::Module::Install;

BEGIN {
    my $mi = "inc/Module/Install.pm";
    push @INC, '.' if $INC[-1] ne '.';
    if( -e "./$mi") {
        require "./$mi";
    }
    else {
        die("Could not find inc/Module/Install.pm during module installation.");
    }
}
