It's all about removing resistance and raising the level of professionalism. D isn't a hobby project and shouldn't act like one. This is an obvious barrier that's worth removing. In this day and age of rampant actively dangerous software, it's an obvious improvement to sign it and make the strong claim that this is produced and vended by the d foundation and we vouch for it's contents. We already do for some (all?) of the posix distribution bundles.
Well said, thanks.
