Maybe marking everything as needing 5.8 or later isn't the right thing to do. E.g. the git-*cvs*.perl code mostly isn't touched, but cvsexportcommit does use Git.pm, so that would also need to be pinned at 5.6 if cvsexportcommit was.

The issue isn't that we don't have a workaround for individual bits like open(my $fh, '-|', @list), but rather that keeping all of the code 5.6 compatible is a burden on ongoing maintenance for a very marginal benefit.
