Discounted 2nd and further licensing

Discounted multiple licensing.

I'll sidestep the free request. I don't really agree with it and wouldn't ask for that. However, as the related request points out users are investing into a platform by purchasing and agreeing to a licensing subscription.
How about discounting further licenses? Say 50% off for the second, 66% on the third through 5th.
Up to 5.
This rewards loyalty, increases revenue, and makes life easier for the end user.
