WTH can't I increment/decrement number entities?

I would like to change the value of some number entities with + / - buttons on a touchscreen since the slider is hard to use.

I can increment/decrement almost every slider looking input in Home Assistant with a servicecall except for the number entity.

For example these can be changed in steps:
media_player.volume_up/down, input_number.increment/decrement, counter.increment/decrement, light.turn_on(brightness_step_pct: 10), fan.increase/decrease_speed

But there is no number.increment/decrement :frowning:

This can probably be worked around with some templates magic, but it would be simpler and more consistent if there was a number.increment/decrement like for the other entities.

It’s there in the HACS Spook but it’s not by default. Never needed it (yet), but it kinda makes sense to have it by default I guess.
