"Shaver sockets can be install a shaver socket either by connecting to a
ring main with a junction box (see Adding a spur to a ring circuit from
a junction box) or from an earthed lighting socket. The spur from the
ring main must be fitted with a 3amp fused connection unit before
connecting to the shaver socket (see Fitting a Fused Connection unit).
The fused connection unit should never be installed in the bathroom.

Connection from a lighting circuit can be made directly, but must be
earthed. "

Firstly, is this up to date?

If so, it seems I have two simple options for the upstairs bathroom

(1) Drop a cable down from the loft which comes off the upstairs
lighting circuit
(2) Spur off the upstairs ring main and put the fused connection unit in
the wall outside the bathroom.

Going off the lighting seems cheaper and simpler.
What are the downsides?

I don't see a problem with tapping into the lighting circuit (ignoring
Part P, of course!). Many bathroom lights have shaver sockets built in.
[Some of these are only live when the light is on - which is a pain if
you want to leave things like electric toothbrushes charging. (I had to
re-engineer mine!)]
