Hi, Mr Jack.

Yeah, I wouldn't use the Encyclopedia Britannica as a source for biological terminology.
Encyclopedia Britannica is just the source I chose to cite because the definition was concise and straightforward. Their way of presenting it seems to be pretty pervasive, though.
For example,
here is an online database associated with an evolutionary biology textbook from Blackwell Publishing.
Most of what I could find says that either neoteny is a type of paedomorphosis, or that paedomorphosis is a symptom of multiple genetic conditions, which are referred to as neoteny (slowing of somatic maturation) or progenesis (speeding up of sexual maturation).
I haven't seen anything like the production/receptor dichotomy you were talking about earlier, but I admittedly haven't put a lot of effort into it yet.
Anyway, I see the distinction you're making with your argument, and I'm really just quibbling the terminology here. It's no big deal.
