Why go all the way to Mansion House?

Clive Feather states that lineside shielding for 1973TS is only
available on the District between Ealing Common and Gloucester Road.
Unless shielding has been extended to Mansion House, the signalling is
going to go out to lunch if a 73TS is turned during traffic hours.
Why not go via the Cromwell Triangle instead? Or even Lillie Bridge?

I think reversing at Gloucester Road would mean wrong-direction running
on the inner Circle track to High St Kensington. Is that permitted? (or
is can trains cross from Glos Rd inner Circle back to the outer circle?)

Alternatively, going the other way around the triangle, you'd have to
run wrong-direction on the outer Circle track.

Lillie Bridge wouldn't result in a turn - the train would go in with
whatever end (let's say it's A) at the south end of the depot, but could
only leave the way it came or to Olympia, where A would be at the south
end. Leaving Olympia you would travel to Earl's Court, with no turn
having taken place.

Mansion House, as the first point with a reversing siding, is probably
easier operationally than reversing at the other points with a crossover
(South Kensington and Embankment).
