Actually it makes complete sense.  Flint was always a lower cost solution to the flame/inferno.  Mainly it can only output 8bit files.  .tga  ect..
 
 
 Flame was capped at  HD resolution  8-10bit  could also do 2k   ( octane, onyx, tezro)
 
 Inferno could handle  2k/4k  (onyx)
 
 Flint  (standard def) could handle hd but was way too slow. (indigo, o2, octane)  there was also a version re-named for the o2 called Effect option2
 
 
 flint also did not have a dedicated stone array.
 
 
 Flint could also be running from any decent  o2 and use the built in i/o or the SDI addon board
 
 
 
 now a days it hasnt changed much.
 
 
 flint is still capped at 8-bit on linux,  handles  HD
 
 flame can go up to 4k on linux  (is capped at 4 cpu's)
 
 Inferno  has no limit and can use like 24+ cpu's if you got them
 
 
 not cores, but full cpus
 
 
 running flint with 64megs of ram sucked
