It doesn't look like you left out anything critical. Generally, my philosophy
is to throw out what I don't use. Any bugs in code that isn't there don't
bother me. That holds not only for the kernel but also for userland. So look
at /etc/src.conf as well!

I would chuck the COMPAT_FREEBSD[456] options on a system without old
binaries, and add GEOM_ELI for disk encryption (this also needs the crypto
device). Since I'm not using 32-bits stuff on my amd64 system, I removed
COMPAT_IA32 (and excluded the lib32 stuff in src.conf). I also removed SCTP,
and never missed it. For my daily use system I remove all debugging stuff;
a desktop, I tend to remove NFSSERVER. I do add the DEVICE_POLLING option.

If you are using it as a desktop and have a supported video card, add the agp,
drm and [type-of-card]drm devices or modules. And the appropriate sound drivers.
