I agree on the principle.

However the traces that exists in the code at this moment are
debug traces. They mostly exist so that you can debug the code
if somehow stack walking acts weirdly in some situation and
you cannot figure why, and suspect something might be wrong
in the native implementation. If I'm not mistaken the trace
that exist today are on the verbose path (at every frame).

To have traces at info level we would need to add new traces.
I am not convinced we should do this just for the purpose of
having something to log at the info level.
