Custom property with type `number` and restricted range?



We had been setting up a custom property for our partners in HubSpot with a type of number and a set of possible values (0 through 10). It used to be possible to create this property (we have some partners whose HubSpot accounts have it like this), but it seems that at some point (around late February 2017) this stopped working and we are now getting this error when we try to create the property:

  "message":"Property 'delighted_nps' of type 'number' cannot have options.",

Is this new behavior the expected permanent behavior, or is this a temporary situation?
