My opinion on this is that the kernel should be the ground on which userspace
should always work.
Features should be taken out with bug reports demonstrating breakage in
general usage, slowdowns or security risks.
Another important point of view should be the maintenance required to support
these seldom used features and I have nothing to comment on this.
Specifically regarding slowdowns, my layman opinion on this is that they are
meaningless in the general usage of the -ARCH kernel.
If taking out theoretically useful features out of the kernel means that in
the end we gain 2 Mb of free memory or Apache is able to sustain 10500
connections instead of 10000 I personally don't see it as good bargain.
Building a personal or an AUR linux package is easy. Maintaining one is a lot
harder. The most important thing that is lost in this process is the community
support. One cannot compare the scrutiny and the testing of any AUR linux
package with those of the -ARCH kernel.
That being said I'd like to read and help test a before and after kernel in
regards to performance or any other concerning factor.
