The RPG-7 is still kind of adequate, but there's certainly room for upgrades. Warsaw Pact militaries also did have weapons like the RPG-18, and the RPG-76 (a folding rocket launcher), and the RPG-18 in particular still sees use today.

I know that counter charges get used to kill off most of the backblast on some weapons and munitions, older ones like the Panzerfaust 3 uses a brick of compressed plastic chips, later variants of the AT4 and M72 LAW use salt water. There's also the fabled IRA launcher using packets of biscuits as a counter charge.

Do things like that reduce the concussive effect to any degree, or is it a losing proposition from that point of view and its sole benefit is reduction in backblast?

A weapon so convenient and useful that the Russians made a close copy of it, variants of which they still use to this day.
