From the ingame descriptions:
"A small directed explosive designed to knock down walls."
"The Shaped Charge has a limited range and area of effect and will not cause injuries, even when loaded in a Grenade Launcher. It is very loud and will alert nearby enemies. For the purposes of perks, it is treated as a support grenade."
"Destroys environmental objects."
So I guess its meant to provide alternative means to get into or out of a building because most grenades in LW2 do no longer cause sufficient/predictable environmental damage?
Is there any other, may more specific use case? Does it destroy environmental object that are indestructible otherwise?

Yes, it's exactly for extreme environmental damage!
It destroys pretty much everything (except maybe some load bearing pylons) but it has a very short range so it's kind of a high risk - high reward situation.
I usually use it when I have enemies concentrated in a spot, behind heavy cover, who just won't die. I approach, expose my soldier and throw the grenade betting on the fact that I will absolutely kill everyone after they're exposed! (risky bet)
