I'll have to crank on the altimeter next time I fly and see how far I can get mine to go. In the 800XP we have a limitation that you can't take off or land if the pressure altitude is less than -2,000' or more than 13,000'.

One thing that has to be considered is the cost factor. If you have EFIS it probably doesn't cost any more to incorporate settings beyond 31". If you have steam gauges, you will be paying money for something you may never use. Those mechanical gauges have lots of little parts and reducing their range of adjustment would make things simpler overall. This usually means cheaper.
