WTH - Why does assist/intent not support fan set percentage

Seems odd to me that Assist can set the percentage of the fan but can a light?

Trying to get rid of Siri and Alexia which can both voice assist setting the fan speeds…

Thanks,

It may depend on the device and/or fan that you use.
I have 4 ceiling fans with ZWave Fan switches and I have 3 speeds that can be controlled in HA.

my fans are working fine in HA. It’s the assist and intents that do not allow a set percentage (speed).
