Even if it was true, why would I stick with armor and only have to deal with it on the campaign map when I can pick shields and not deal with it at all? It's not like lowtech ships get you something in return. Sure you can use shunt and get a bit more dissipation, but their dissipation is lower to begin with, so they really only break even. And then they're slower, less maneouverable and burn more fuel.
It's like Hardened Shields and Heavy Armor. Hardened Shields works equally well on every ship with no downside, while heavy armor beneftis smaller ships(which need it the most) less and has a downside to boot if S-modded in(and it costs significantly more OP too so you definitely want to S-mod it in) Just... why bother? Sure, kinetics are great but you can get these on midline ships that don't have to pay for it with... everything.
