It would be better if you add a filter/hook to permit custom field's to add tooltip option on form editor page.
I have some custom field developed for specific reason. If you add a function which can be publicly accessible will help to add tooltip option's on my fields.
Thanks
not totally sure what you mean by "custom fields", but there is a filter to add / remove which field types have the tooltip available to it. the filter is gf_tooltips_allowed_fields
