If you have a full class A (ie. /8 or 10.x.x.x) then you conceivably have 10's of thousands (or more) MACs to potentially keep up with and setup spanning trees for.
Wait 'till you start working with IPv6 networks, where you can have up to 2^64 devices on a subnet!
Of course, practical considerations may limit that somewhat. ;-)
I have a /56 IPv6 subnet, which can be split into 256 /64 subnets.
I'm a IPv6 neophyte, but I have wondered about that. Since IPv6 is 128 bits I think, a single /64 subnet is as big as the public facing Internet is today. (ie. Ignoring private IP space like 10.x.x.x). I have a hard time fathoming how something that big can be managed without some form of hierarchy.
