#14 on 20A lighting circuit

I found some 14awg used as switch legs/ travelers for lighting on a 20a circuit. Old installation. Was this ever an acceptable practice? Would you be changing this if practical? (its not practical).

Someone on the site mentioned that it was popular years ago but I've never heard of it or run into it. If practical then yes.... it should be replaced.

(I clarified the title a little bit)

I see this all the time around here. It becomes a real pita and I get stuck replacing it.

Right or wrong , is is SOP around here . The AHJ apparently has no problem with it on Romex jobs .

On conduit jobs , it is all # 12 on 20 amp circuits .

Do not yell at me , I am not the conductor or the engineer on the train .

Some places use 15 amp circuits for lites and 20 amp circuits for receptacles . Best I remember , by code , 15 amp circuits are legal for receptacle circuits , except the " required / dedicated " circuits ?

But we do not do it that way .

God bless
