hyperbole is not constructive

creaky as it is, this is an informational draft which is documenting an
extremely widely used and distributed protocol.  no one is gonna change
millions of devices and thousands of servers for tweaks.  no one moves
for a 10% improvement, especially if there is no functional improvement.

we need to document it so we can put this in the can and move forward to
modernizing it.  then, if we have a seriously functionally improved and
modernized protocol, we will start the 42 year process of rolling it
out.
