Did you use a rice cooker? Rice cookers operate by “sensing“ when all the water is boiled off, by means of a temperature sensor that detects when the temp goes above 100°C. (If you have just the right ratio of water in there, this is what you want.)

Having too much water in a rice cooker is indeed terrible for the end result, but only due to the nature of how a rice cooker operates… I’m sure if you treat it like pasta and take it off the pot after 10 minutes or so ( not waiting for the water to boil away) you’d get much better results.
