No self-destruct for weapons

[Taz-in-Space]

I just tried out my new mod for weapons and found out that you can code for self-destructing weapons, but you do not get them to self-destruct
via the seIV combat routine.
I am assuming that the destroyed after use for the supply and movement components is handled by special routines not available to the combat engine.
Is that the only special ability not supported by the combat engine or are there others?
Is there any possibility that a future program update will address this oversight?
