I respectfully disagree. If the goal of Devshares is to enable rigorous testing, and the testers will be mostly devs or large BTS holders, it makes little sense to sharedrop 100% to them. It would give testers a perverse incentive to not do any really revealing tests in the wild that could break things and jeopardize the value of their Devshares.
Having said that, I think a nonzero allocation to BTS would be reasonable. The balanced sharedrop originally proposed (1/3 to each of BTS, PTS, AGS) keeps things simple and makes sense to me.
