True, but when the H&C line trains are often not even displayed, and
even then often the Whitechapel only service is available, so getting
closer to Liverpool Street is a natural move - and sometimes I have,
depending on which trains are available, gone to Aldgate and legged it
to Aldgate East to get the District or changed at Tower Hill for the
same effect.

Yes, an Aldgate interchange would allow you to take a Circle/Met. to
Aldgate and then walk through long enough passages to miss the following
H&C train, but I'm not sure that there's a great public benefit there.

If the train were following closely enough then I reckon it would show
up on the indicators. Otherwise I could get the more frequent through
District service.

Whilst not the greatest public benefit, a single combined Aldgate
station could work better than the current one.
