GENERIC - Raising the bar

*BSD's have long shipped with a GENERIC kernel conf that will work on
386 and any newer x86.
Manual editing has been required to optimize for 486/586, K6, and
various flavors of Pentium onward.
Over time, even embedded systems have moved to at least 486/586 levels.
Further, embedded is not only a small market for a *BSD, it is more
likely to be QNX,
eCos, or other micro- RTOS turf - not even all that much Linux ground.
DragonFlyBSD is a modern project.
Might it not be advantageous to optimize the GENERIC build for no less
than 'Pentium-class'?
Removing the ability to option back down-scale is not likely to have
significant
impact, but could make certain tasks that can take advantage of chipset
features easier to do well.
