making it derived won't include Custom-mode options anyway? Yes, but we 
could arrange for Custom-mode to set the right values, I think. Although 
maybe it's not worth it. > I made it a major mode but not derived from

can use derived-mode-add-parents to be clear that we consider 
Custom-mode a parent of this new mode. Some comments below: >>From

Customize Directory Local Variables in the current directory." Please 
mention that it runs Custom-mode-hook too. Let's see if somebody else 
has an opinion. I'm on a trip for the weekend, so it won't be until next 
week that I can install this.
