My belief is that these have been largely due to bugs in Netfilter where
valid packets are incorrectly assigned the INVALID state rather than the
ESTABLISHED state. As Netfilter has gotten better, this problem has
gotten a lot less burdensome. I currently only have one of these rules
for TCP and it is for active mode FTP. And that one is to handle PASV
commands that are split between packets rather than netfilter problems.
