I suspect the currently-known limits are actual limits. There may be exceptions for theoretical constructs, but the information analysis approach seems to be pretty strong.
Note that these limits aren’t all that limiting. There’s a LOT of stuff in our light cone, and a LOT of behaviors and information/experiences we haven’t considered, even within out currently-known constraints.

https://en.wikipedia.org/wiki/Black_hole_information_paradox is a reasonable writeup of the approach for black hole physics. There are similar information-centric views of quantum computation and tunneling.
