Off the top of my head, I think Search::Xapian // Xapian.pm was
the main thing that was missing from CentOS 7.  Does Fedora have
that?

(disclaimer: I don't care for Docker, seems like a giant waste
of space and bandwidth compared to just using the distro)

Email::MIME isn't used at all outside of tests (but it's widely packaged).
No idea why libcap2-bin and vim are explicit dependencies (any
editor will do).  Don't need Plack for lei, either.

No need for Net::Server nor Parse::RecDescent for lei.  I don't
use Net::Server at all outside of tests, since I use systemd.

Email::Address::XS and TimeDate can be useful for messed up
messages, but low importance (I think they're widely packaged).
E:A:X and P:RD are required for -imapd but nothing else.

Socket::Msghdr makes lei a teeny bit faster, but I don't think
it's worth using another distro or running a compiler to get
since Inline::C is already available in all distros.  Everything
else should be in Fedora...

eatmydata shouldn't be useful outside of development, and
libgit2+pkg-config isn't used by lei, yet
(it is for -httpd/-imapd/-nntpd)
