[Feature Request] JSON file for configuring which blocks can be sit on, and position

[Synthestra]

Having a json file defining what blocks can be sit on, and settings their positions would allow users to allow custom sittable blocks easily without modding knowledge. An example sit.json could be:

{
	"sit": [
		{
			"block": "#minecraft:slabs",
			"properties": {
				"half": "bottom"
			},
			"seat": {
				"x": 0.5,
				"y": 0.25,
				"z": 0.5
			}
		},
		{
			"block": "#minecraft:stairs",
			"properties": {
				"half": "bottom"
			},
			"seat": {
				"x": 0.5,
				"y": 0.25,
				"z": 0.5
			}
		}
	]
}

The "block" perameter would support singular blocks and block tags.
