I noticed the license field of the library.json only takes a string with 1 SPDX identifier. I have a lib that distributes with 3 different licenses. I was wondering how to go about specifying this in the JSON (if possible). I would have guessed that the license field could optionally take a list of strings (all SPDX identifiers) in this scenario.
In the Meantime I have resorted to only specifying 1 of the 3 licenses in the JSON (its not published to PIO registry yet).
