As TV broadcasters gradually switch off their analog transmitters, and viewers update to flat wide screen TVs. through attrition of their ageing analog TV sets; the frame rate conversion will become an issue of converting 50p or 60p to 50i or 60i because even in digital video broadcasting, digital video free to air broadcasts in countries such as Australia transmit in 50i, to maintain compatibility with the older analog system, to allow analog TV users to use HD "set top boxes", to view 1080i or 720i HD wide screen broadcasts as SD "letterbox" images.
Some brands of wide screen HDTVs matched with same brand Blu Ray players, permit Blu Ray movies with 24p play back capability, to be viewed at a cinema frame rate of 24 progressive frames per second.
Indie or studio film makers have the option to potentially release movies directly to Blu Ray, using 24p frames per second.
Film makers using cameras that only offer 23.976p can convert their footage to 24p with a PC/Mac based video editing software to maintain lip sync (synchronisation).
There is no real technical reason why a camera offering 23.976p cannot offer 24p; the restriction is purely a firmware (i.e. the computer program running in the camera) issue.
Some folks in other film making web sites, speculate camera manufacturers offering 24p on their cinematographic/professional cameras and not offering 24p on their prosumer models, do not want sales of their higher cost professional cameras be dented by sales of their lower cost prosumer models. Although these may be opinions without any basis on fact?
