Minecraft bedrock edtion action detecting

I think Minecraft Bedrock Edition should have action detection in commands, I think it would be very useful. For example: I could make a command creation that could detect if you were holding a feather with "execute as @a[hasitem={item=feather,location=slot.weapon.mainhand}] at @s[action={jump}] effect @s levitation 1 1 true" in a repeating always active command block. I think action detecting would be very useful.
