Just a data point from a user:

I would appreciate the consistency of variables named with -function/-predicate suffixes to have a function has a default value. Being able to use add-function on just variables is very convenient (I use it to tweak region-extract-function). The default values also serve as good examples.

As Leo pointed out, in 99% of the cases, nil is not equivalent to
`ignore' in those variables.  And if it were, then what would be the
benefit to use nil instead of using `ignore' as the default value?
