Yes. Now imagine e.g. dissolving pace makers or whatnot.

I wonder what use that would have—maybe healing after heart surgery? Using a pacemaker as a crutch until your heart can beat on its own again?

a pacemaker is admittedly a poor example, but it's also just that: an example. I'm sure there's hosts of medical devices that would benefit from dissolving. Perhaps even devices that are infeasible currently because they don't dissolve.
