There's a limit as to what can be changed on the fly: depending on how
data structures get used. (When re-reading a file it's first necessary
to remove stuff which came from the last read: if that's in use
elsewhere it all breaks....)

It's probably possible to do options, dhcp-range is not possible.
I wonder, would it be best to make the dhcp-hostfile have dhcp-host= and
dhcp-option= lines, like the standard config, or have a different file
for each with the hosts as now, and a --dhcp-optionsfile separate.

See above, that will always need a restart.
