it would only be a pinhole at first, though start to grow quite rapidly(? no idea in what time scale?) and at some point consume the sun quite violently from within, no?
The numerical simulations in the paper go on for a time on the order of the Sun's hydrodynamic time scale, which is tens of millions of years. After that time has elapsed, yes, the star could be completely consumed by the hole.
