Yes, it is a critical distinction.

The reason IP-over-TCP-OPTIONS still mostly works, is that it is
so hard to deploy and use that it has not become a big enough
problem, just like almost no companies have RFC1194 filters in place.

Being able to download a "unfiltering" version of a browser which
tunnels contraband through port 80 or 443 will be met with an
entirely different kind of resistance.

Never attribute to malice what can adequately be explained by incompetence.
