I think it's pretty misleading to paint this as a Klingon issue with the ammount of Sci fleet/MVAM/fleet support I see in PVP. Starfleet spams too.
Not to mention mines and scorpions. Neither of those have much effect other than making targeting difficult, so you can be pretty sure that when someone bothers to equip scorpions or is circling around in a cloud of mines, they are doing it specifically for the spam.
I wouldn't mind a general reduction in spam (even if numbers are reduced but power is increased), but it's definitely not just Klingons doing it. I'm a bit more tolerant of carriers doing it, since it's not possible to have a carrier without having it carry something.
I kind of think this is one of those divisions between PvE-players and PvP-players -- PvE players seem to love combat pets. If you've played other PvP games, think about how many really did a good job of balancing pet classes. As a rule, pet classes are always either too strong or too weak in PvP, because either the player is good without the pets so the pets make them too strong, or the player is balanced around having the pets most of the time so they are too weak when the pets get killed. The other problem is that either the pets are too vulnerable so players kill them a lot, or they are nearly as tough as another player so they don't get killed at all. I can't think of an MMO where they got PvP pets right, they *always* alternate between being underpowered and overpowered. Combat pets are one of those things that really ought to be left out if you design a PvP game -- no one has ever done them well.
