One other point: the changes add mechanism, and that mechanism has a
cost (in maintenance if nothing else) -- if the changes are more or
less pointless as a number of people think, then we'd be paying that
cost for zero or negligible benefit. That does seem like a valid
reason to oppose such changes.
for my part during the above-mentioned squabble I made it pretty clear
that I think aggressive use of kernel modules is at best tilting at
windmills; I stand by that position, but I'm not really interested in
fighting about it at the moment so I won't stick my oar in any
further.
