That's a good point: there's no rule that says you have to run a distro-built kernel, even in a production environment. A customized kernel with unneeded features trimmed may help matters. (For instance, I have no need for most of the drivers or filesystems.)
LinuxCon: Kernel roundtable covers more than just bloat

Linus was talking about some kind of bloat that makes the kernel slower. I don't think removing device driver or filesystem driver modules from the disk or configuring out most of the configurable features speeds things up.
