Good point. The contiguous requirement is valid only for normative registers, where the device has no choice but to follow the standard. For the imp-def part where regmap would typically be used, then indeed there is no restriction, chip implementers can do whatever they want. I have a vague memory that regmap was only intended to be used for this latter case, but Vinod and team should clarify this.
Right now it is used by codec for imp-def area. We do plan to add for all registers eventually
Thanks
