Well... it seems fairly cut and dry to me. Maneuvering, Stealth, Targeting all use "specific drone/weapon" language. Clearsight, EW, and evasion do not.
I could see treating Evasion as being drone-specific as a reasonable house rule/adjudication. Personally I've got a soft spot for riggers, and Autosofts are already expensive enough as is. Note that unless you're sharing an Autosoft from a RCC, you have to re-buy the same Autosoft anyway over and over, drone by drone. Having to re-buy some very combat relevant Autosofts on top of when you simply change out a destroyed X model for a destroyed Y model adds some un-fun book-keeping to playing a rigger. Therefore I'd prefer to go the other way... make Targeting be the only Autosoft that's device specific.
