Dunno about Linux but OPNsense forked off them a while back. Can't speak about the rest but I know that fq_codel is supported because I use that myself.
(Frankly, I switched away from pfSense because I like the OPNsense developers and surrounding community better. I'm more confident that if they haven't already addressed those defects, they will soon or they'll welcome patches that do.)
