Every five years or so i go buy one of those pre-made showers. Come back to the job, unpack it, then pack it back up and return it.
I have Never installed one of those bases because I will not put my name on something I feel will leak.
As for your question as to pouring the concrete afterwords. Not sure the point in doing that. I set tubs in tile mastic, or the such, some guys use drywall mud. That way the tub is supported evenly.
Nowadays it is mostly about the lowest bid someone receives. It seems to me that people do not have the attention span to be educated on why something is being done a certain way. How cutting corners will cost more to fix later. The public demands cheap prices so this is what they get. Cheap products put in by people that give the lowest bid.
