So, I’m in need of a build knob to control the bloat, and/or having an alternative boot loader without geli/skein/crypto support compiled in. Would you be opposed to the work?

We have this problem at work too.  We deal with it by defining the
following in src.conf.  The build system already knows about this
variable, though it isn't in src.conf's manpage.

LOADER_NO_GELI_SUPPORT=1
