iIt would be awesome if you could ask the question on their official github issues. It would be tracked by them, hopefully. I masked similar question about ctlr + X/C command usage.. and got satisfactory response..

of course. you can use ssh in powershell already without putty

That is not what I asked. I asked how well this new terminal emulates DEC VT-family of terminals.

I'm disappointed you're getting downvoted, since proper terminal emulation is something I'd like in the Windows console as well.

It's a popular thing to downvote me, but that's the history of the entire mankind, to punish those who ask the critical questions or think differently from the mainstream. I don't really care any more: if I want to ask my question I will ask it, the way I want to.

It would be useful if the default Windows™️ terminal had proper emulation, agreed. That would bring it closer to UNIX®️ and make Windows™️ much more useful. That is logical but as you saw not obvious, especially not around here.

At the link below I believe.
