Integer and Boolean inputs for Shader Node Groups

We have Integers and Booleans in Geometry Nodes but sadly they are still missing from shader nodes.

There are many times when I want to use a boolean to switch between two values, or use an integer to select a discrete value.

Working around this using floats is very inconvenient, as you can't have a checkbox for booleans or easily increment/decrement whole integer values in the node group input.

Compositor nodes, texture nodes, and all other node editors should have them as well.
