We went over this some months back, and I don't believe anyone could come up
with a code violation, which seems strange to me, but I know I couldn't find
one

Is it a code violation, certainly.
Will your house explode in flames? no.
14ga wire will carry 20a all day long, even at the 60c rating. 310.16
says so BUT 240.4(D) says you shall protect it with a 15a breaker to
build in the 80% safety factor. If the real load is limited to a
single luminaire it is not really a hazard but it is still against
code.
