There may be ability limitations dependent on the individual as well. Jedi and Lensmen are exceptional to be sure to begin with, but perhaps the man or woman who has the innate will, tenacity, skill, talent, drive, and as Doc Smith would perhaps say "the starkly cosmic scope of mind and body" to master both the Force AND the Lens is one of a few dozen, at most? Plus, it's a given it's going to take the individual a while to pull it off. Decades, centuries even...

Seems like a vanishingly small group of people - not impossible obviously, just small, perhaps almost another evolutionary playing field altogether.
