Well, maybe, but that would require SEXPs.
What I want are improvements to CM dispenser (the one fired by "x" key).
This would come in handy for any mods that use custom CMs, or even modellers who don't want their models to spawn CMs from the center and from a modelled dispenser instead (I guess that even a few Mediavps models could use this).
I think that if $Swarm is too difficult to make work on CMs, then maybe a new field could be a good idea ($CMBurst: , for example), which would do the same thing as swarm, only in CM dispenser-friendly way. Or perhaps a new burst flag (though I don't know if $Burst Shots work on CMs either), "Force Burst", which would make a weapon always fire a full burst (in fact, this flag could be fun for many other reasons, but that's irrevalant).
As for AP flyby, it was, IIRC, implemented by WCS team for WCS and it's most likely still used by them.
