TADS is hardly modern. It’s actually the oldest VM based platform from the early 90’s.

Well, TADS is older than Inform, yes, but the whole idea of VM-based platforms for adventures originated from Infocom's Z-machine starting with Zork I in 1980 -- it's what let them basically release their games for every platform current in the US in the 1980s.

But not publicly available as a platform.
