While the Trial framework is capable of doing A/B testing (and historically started out for that purpose), it is fundamentally an asset delivery mechanism, and is mostly used for that (i.e. I suspect that most of the domains using Trial currently have no "B" to pair with their "A").

And some of the differentiation that IS being done is not A/B testing in the usual sense of the word. i.e. if one particular hardware model needs a different version of an asset, those models can be assigned to a separate set, but that does not really make it an A/B test.
