Yes, you've grasped the reason for leaving the old driver in, so people
can use their computers. Because when there is a new driver for
previously unsupported hardware people will be glad to put time into
debugging it to make the hardware useful. But when you take out a
working driver because you (ie. the responsible developer) have a new
idea which interests you, users don't want to use it because they have
something which works, so you take out the working driver to make work
for the users and create what you call a "better new driver" below.
The old driver wasn't requiring any resources to maintain, the old
hardware wasn't changing, there was no particular benefit to users in
breaking their configuration. This disregard for the users just gives
Linux critics an arguing point, "the next new kernel may withdraw
support for your hardware." Isn't that why 2.6.16 is still being
maintained? Nobody (sane) expects new drivers to be perfect, they just
don't expect the working drivers to be disabled.
"Better" is a very subjective thing, you see elegance of design perhaps,
I see works or not, and when I have to use statistical methods to see
latency or CPU overhead benefits, I frankly don't care.
Removing a working driver without a fully functional replacement forces
people to stop upgrading their kernel, or start maintaining old drivers
out of line. Problems of the "just occasionally goes away" type can take
months to debug, the load can't be duplicated in most cases, and there's
no log or oops data to help.
Where does sky2 come in? Does this mean the the recent suggestion to
"just change to skge and stop complaining" is also wrong?
