And where is the RadioShack needed for the adapters for those one room 
school houses using RPIs in underdeveloped countries? It doesn't seem 
mysterious why the Raspberry Pi folks use the most common, standard 
connectors they can find (anybody else notice the main header matches 
the old PC floppy disk drive signal cables?).

But I agree 100% with John's point that it seems impossible that there 
would be no modern alternative to the RJ45 after all this time. I'll bet 
there are some amusing gossip stories about attempts to change this 
situation.

But going to the other extreme of build vs buy, the truth is that as 
long as you can control impedance and deal with EMI if that's relevant 
you can arrange your own connections. With amateur radio this is 
standard operating procedure, most especially at high frequencies.
