Having the default and minimum the same value is a great idea - especially for resource constrained implementations that want to "ignore a setting from the other side". What value do you suggest though? I would be really, really, really surprised if anybody went for 256. For browser implementations, you'd have to wait up to one RTT before you know what the peer actually supports and can send a request safely - or speculatively send larger frames assuming the peer is going to increase from the default setting.

BTW, we still work with micro-controllers with ~100K, where 16K is a significant resource  commitment.
