QOL: Hashcheck on the blueprints.

[Raymoo]

I don't think it is "trivial to implement", he would need to implement the mechanisms for sending the hash listing and storing them on the server and client. Also might need a add a way to request individual blueprint entries, which might not exist yet since currently everything is downloaded at once. And to be efficient you would want to be able to do a batch request for multiple entries so that SoH doesn't have to make many individual requests.

IMO none of that is hard, but it's also not "trivial". I think developers use that word too loosely and it should be reserved for cases where a change actually requires only minimal dev time.
