In general you are right but in a discussion about relativistic mass the unqualified word "mass" is not an optimal choice.
That depends on what your optimality criteria are. Mine is to maximize education about modern physics, in which case it is probably close to optimal to explain that the modern scientific community uses the unqualified word "mass" to refer to "invariant mass" and then using it consistently.

Could we? The majority of physicists would need to agree with the new name. That's very unlikely.
This is an odd response given your previous comments in this thread. You seem to recognize that the important part of the name is the agreement of practicing physicists, but at the same time resist what practicing physicists have agreed on.

Minimization of miscommunication. If someone wants to speak about relativistic mass he is obviously not full compliant with the current conventions. Simply using "mass" would most likely result in confusions with the topic of the discussion. It's not worth to take that risk just to avoid the little redundancy in "invariant mass" or "rest mass" .

You got me wrong. I have no problems with the conventions for the terms of mass and energy. I just believe that they are not a result of any fundamental reason. It's a random choice from different possibilities.

Which is why the current conventions were carefully explained in post 3. At that point communication is clear.

Agreed.
