Presumably the flare connections at master cylinder and at flex hoses compression fittings are not considered compression fittings? Is it the non-flared compression fittings with ferrules that are illegal? Autozone sells these ones for brake use.

My 300D has always been under-sprayed by Krown or Rustcheck . But when doing a rust restoration last year (documented in bodywork forum), I had underside of car steam cleaned and I painted everything I could get at including fuel and brake lines with DOM16 (similar to POR15 and sold by NAPA Canada). Weak spot is always under the clips and I did have fuel lines corrode under clips a few years ago.

A few years back there was one heck of a lot of chat on the forum about the legality of different brake pipe joints - I came to the conclusion it is best to check locally. It seems to be different all over North America and the rest of the world.
