What is valuable in your opnion in that case?
Demonstrating that said feature is needed and useful, not using "but somebody might find it useful" as an argument:
But this feature may be greatly in demand. For example by modmakers. This would be very interesting mechanic.
I could assert that feature XYZ "may also be in great demand" and that it would be "interesting". That alone isn't an argument that it should be implemented, because I can't show that either is actually the case.
Sorry didn't caught that, please explain.

In 'X-Com Files ' mod there is some kind of burst shooting but its made as a single shot and shoot looks like bunch of bullets. Something like that.
Unless I'm misunderstading you you're stating that you want "something like that", i.e. something that is already implemented.
