I've been out of the loop for a while, but devfs(8) has always been
able to read a ruleset from a file:

	devfs rule -s 10 add - < yourfile

This can't be used to read *multiple* rulesets from one file, but I
think it's better to have one file per ruleset anyway.  Non-"add"
commands might need their own syntax, though.

ipfw(8) doesn't actually read from a file; rc.firewall calls ${fwcmd}
explicitly for each rule.  devfs(8) easily supports this model.
