I dont get why this baffles people in the business.
If I was a VFX start-up and didnt know better, yes folks that happens all the time, I would opt FCPX for its simplicity.
Back in the day (from my background), most 3D/Motion design houses didnt have an Avid or Media100.
They had Premiere (pre CS) as a simple editor.
This was also the norm on the Unix side, sorry forgot the software that was used then.
