I guess the question really is:

What it the most important concept you are relaying to the 
programmer by the use of that term?

That they 'must use it'.

Or, that they 'cannot discard it'.

They seem like two different concepts to me.

I don't believe that using nodiscard in C++, means you must use 
it.

If in D, it means you must use it, then 'mustuse' makes more 
sense.

If not, then stick with what people already know, is my advice.
