imv uses a2x, a python script provided by app-text/asciidoc, to generate man pages. There is a meson feature option to choose enable man pages or not. So I think it will be nice if users can toggle it via a man use flag or something.
man pages aren't supposed to e guarded behind a USE per Gentoo policy [1] If this was a more problematic dependency (e.g. asciidoctor which pulls the whole ruby stack), I'd have considered adding pre-generated man pages but asciidoc is rather trivial and IMHO not worth an extra maintenance burden to skip a build-only dep. Not that it'd be much of one right now considering imv upstream is currently dead and looking for a new maintainer, so releases are very rare.

Oh sorry. I didn't notice the policy. Thank you for your help.
