I was wondering if we could add several other customization types in
`wid-edit.el`.
One of the widget (or type), I would like to get is major-mode and
probably minor-mode too. Is there any reason why it was never included?
Given we could know if a symbol is a major-mode, would it be okay if I
made a patch for that (to be included in `wid-edit.el`)?

This sounds useful to me.
I also briefly looked for a general way to say "symbols matching a predicate",
for one-off types similar to the above request. Is that possible?

1. Do you mean for completion when entering a symbol value for a
field? If so, I don't think that has been implemented.
(In fact, it seem that if you try using `M-TAB' in such a
field you get the inappropriate error message "Not in an
editable field", instead of a more appropriate message
telling you that completion is not available in that field.
That seems like a bug in `widget-complete'.)
2. Do you instead mean a way to restrict a field value to be
a symbol that matches a given predicate? If so, yes, you
can do that using custom type `restricted-sexp'.
