Unit number conflict and limit to 31?

[Wallebalboa]

Hi ! running build 105 and when setting (yes i know it should be unique number! ) same unitnumber to multipel nodes will make them to restart with intervals of just a few minutes.. (works fine if unique #).
as i run openHAB MQTT i have a big question of the reason for unit # over all? what is it used for? why is it limited to 31?

there had been a suggestion, to set the unit-nr to the unique-chip ID.
maybe a topic for the wishlist...?

any solution that will not limit number of nodes to 31 is good! Is there any workaround?
i dont really understand what it is used for any how... do a clean MQTT installation need unitnumber at all?
