Chopping up the layer-2 broadcast domain for a given VLAN into smaller pieces via pVLANs can't hurt, either, as long as the hosts have no need to talk to one another - and it has other benefits, as well.
Unless your broadcast storm happens on an untagged vlan. Or unless you're running VTP and also have ipv6 hosts connected to the switch on .1q tagged ports, and consequently have to disable VTP pruning in order to get said ipv6 .1q hosts to be able to talk to each other, and then if you have a broadcast storm on any vlan, it could hose your entire l2 network, because you've disabled vtp pruning.
Anyway, the point is: storm control on customer facing equipment is a basic requirement.
