You have to remember that Howard Armstrong, who "invented" the regen
(he was issued the patent, but it's something you really just trip over
rather than invent). then went on to invent the superheterodyne, which
does seem to have come from deliberate effort. He was disatisfied with
the
regen, which led him to experiment and explore until he came up with the
superhet.

The local oscillator operates on the regenerative principle, so Armstrong
was obviously in a good position to develop the superhet. Fessenden had
discovered heterodyning years before, but he was using Poulsen arc
generators as oscillators.
