And just to be clear as well: I was agreeing with you and just expanding a little bit. :) The hearing world doesn't really get a lot of say in the opinions of the non-hearing world.

Yeah, no matter what if you have a deaf kid you should learn sign or you're kinda crud.

I think my main "concern" would be less on school and government accomodations, and more the culture aspect.
If you're in someplace like New York, you'll probably be able to find a place in a community where they can have deaf friends, teachers who sign natively and all that stuff. You'd probably be able to find someone who has been in the childs position and get their perspective. Probably several.
If you're in someplace that doesn't have that, I think it's a much more difficult question. Being in a situation where you'll have limited options for who you can communicate with via sign and, while doing their best, teachers who have limited resources to convey lessons, and generally much less community you can communicate with easily is a situation where I can see someone having the weigh those realities while not being fully able to take the feedback of other deaf people.
