I agree with this.  In my view, we actually have had consensus
for a long time that extending the SYN is "really hard" (requiring
some creativity), whereas extending the options space on other
packets can be done quite a bit more trivially.

So, the problem is decomposed into 2 parts; the harder part and
the easier part.  EDO is leaving the harder part alone for now;
although it may ultimately be the more useful one to solve.  I
don't see this as a problem with EDO or reason not to do it ...
any future solution for SYNs may differ substantially, but would
seem like it should not impact how options are extended on other
segments.
