The current actions done by domo are unintuitive, hard to understand, and nearly not used Used by only 6 packages, 13 ebuilds Raised in IRC #gentoo-pms
In particular, it's not possible to install for a gettext domain other than ${PN}, which is often not actually what you want (it depends on what the source code declares as the domain) so I simply would not feel safe using it at all. I'm also skeptical since packages which produce .mo files, rather than only .po files, surely have some buildsystem setup already and I believe it unlikely that they will compile them but not install them. It is comparatively quite common for bad Makefiles to compile an executable or library but not install *them*, so other doXXX helpers seem far more useful.
