Ancillary question...
Why was the Hubble placed in the orbit it is in. Pity nobody thought
about access when it was put up. I'd have thought that there could
have been orbits that would be reachable from ISS without the huge
thrust requirements that the current one requires. Or is it just a
case of nobody knew which orbit Iss would use at the time, so then the
question could be asked about the orbit chosen for the ISS??

HST was placed in a 28.45 degree orbit back in the days when that was the
planned orbit for Space Station Freedom, though there was no plan to keep
them in-plane. When SSF became ISS, it was moved to 51.6 degrees to
accommodate the Russians.
