Today I noticed that at least two of the streetname signs are very
large and include a map, showing you where the various house
numbers are.

London has a new campaign to encourage walking, which started just
before the mayoral elections. Could it be associated with that?

One objective of the walking campaign is to reduce overcrowding on
the tubes. In central London, where the tubes are most crowded, a
good many people on the tube would have found it quicker, not to
mention pleasanter, to walk, especially if that had changed trains
for a short second leg of their trip.

Not sure whether Onslow Gardens is a good tube shortcut, though

I don't think it shows where anything is, other than the housenumbers in
Onslow Gardens, which consists of a square with two roads off one corner,
with another crossbar on one of those roads.
