Distortion weapons in 4.0 - What's the status?

So I haven't looked at distortion weapons in quite a few patches. I used to daydream about running distortion weapons + EMP to have a "less than lethal" takedown build on my Raven just for funsies, but last time I tried it they didn't seem to be working quite right.

Are distortion weapons correctly powering down ships/damaging powerplants in 4.0+? Can anyone who's used them recently let me know how they're performing and what issues they still have? I'm suffering a service outage in my area so I can't really login to try them out myself right now and would appreciate some insight!
