Cmon, we don't even have the chakra necessary to get any real use out of the summoning scrolls! Stop being blinded by the useless for now shiny!
Summons can summon themselves, and do reverse summoning as they wish. With their own chakra. They can teach. They can send and receive messages. They were allies of our clan, likely for generations. Right now they think all of Uchihas are
dead. Uchihas they were likely friends with, or at least loyal to. Even if we can't summon anyone important, and with Naruto + Chakra storage seals it's very arguable if that's the case (Because sharing chakra for a jutsu? Is not actually that strange of a concept in canon, actually), we can summon someone who can then relay a message to the important people in the summon's clan. From there on, I expect us to soon get a responsible adult who would look after us.
Maybe, but Itachi also summons them so they know he's alive. And the crows are working for him.
Itachi summons crows in shippuden. Even if he has already signed the scroll (not a given), it's still one clan out of four who knows any Uchiha is alive, and might know (only
might) what happened.
Do storage seals work for people other than the maker? Honest question, because I don't remember when they were used in canon.
As far as I know, they weren't, ever, used in canon, but sharing chakra for jutsu was done on several occasions with no prep or specialized training (Gamabunta gave Naruto his chakra so Naruto could do a henge and turn Gamabunta into a kyuubi look-alike).
Also, a plan modification. I'll go with ravens, they are more wind associated in my mind, and hawks are Sasuke's thing.
