My objection re: pollution is more to the point that this propagation of mechanisms that are inherently "package manager control flow" into USE flags is an anti-feature. USE="test" is already objectionable enough, but adding Yet Another Use Flag, and potentially, adding it to every package is just asking for trouble, asking for more ways for the portage resolver to get confused, asking for more ways for annoying auto-unmask mechanics to fire, and asking for more reasons for people to have to come to #gentoo and have somebody hold their hand trying to make sense of the huge mountain of spew ( which is potentially unrelated to the real problem, obscured by portage pushing past the problem before barfing ), and I'd rather we reduced that problem, not expanded on it. Like for instance, a common problem is USE="test" introducing cycles, some of them are unavoidable, and portage is completely unable to provide a working merge plan, because it can't even *consider* the option of temporarily disabling USE="test" to resolve the cycle, and then restoring USE="test" and building it a second time. End Users who want to employ FEATURES="test" blanket wide across portage have to hand-curate a collection of tools and hacks to make it work. Obviously, this is also exacerbated as portage can't soft-install a package or a collection of packages, for the purpose of testing integrity, prior to deploying them to the system, which would be necessary for X -> Y -> Z -> X to proceed far enough that X can be rebuilt, and tested, without potentially deploying a broken X[-test] to the system, and without potentially deploying Y and Z, which could in turn be broken due to X[-test] not throwing a failing test. If portage could do that, there's so many other things it could be doing too ... Like, ( and this is getting a bit OT ): Auto-Reaping build-only dependencies as soon as no targets in the merge plan need them.
