bash-completion (useflag) doesn't really install the completions provided by packages. I've to run bash-completion-config or eselect to install them. There should be a way to install them by default.

We're not doing it by default because it can make bash pretty slow if you have a lot of packages installed. The post install messages for any package providing completion should tell you how to enable completion.

I have ~200 completion modules turned on and bash runs fine as far as speed is concerned. I have the bash-completion USE flag on, because I want to have that feature available. For everything, of course - who knows what command I'll use tomorrow. Having to enable bashcomp modules manually is a nuisance to me. Sure, I've got a powerful CPU (read: common; not embedded), but most people do. Those who don't are a minority, AFAIK, and will have to turn off the modules manually - if they use bashcomp at all, that is.
