It's the same, regardless of the nature of the broadcast domain.
If the broadcast domain (VLAN, Subnet)has too many hosts, you end up eating a lot of bandwidth (too many broadcasts) ... and if the broadcast domain spans one or more WAN links, you've wastd a lot of expensive bandwidth.
The other downside to too many broadcasts is that the nature of the broadcast means that all hosts that hear it (everything in teh broadcast domain) must accept the traffic, and process it up the stack, at least to a point where it can decide that it doesn't apply to that host and it can throw the traffic away (like an ARP, DHCP request, multicasts ....)
So, if you decide you want to have a single flat network with a couple thousand hosts on it, and it's going to span several physical locations, plan on running at about 20% efficiency, and for Spanning-tree convergence to take a loooooooooong time.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
