OK, so that appears to be sufficiently air-gapped off at Abbey Wood
to mean TfL could run that service independently of Network Rail
potentially having to approve any of the timetable from Abbey Wood to
Paddington.

Operationally, yes. Is there any attempt to provide good connections
for passengers, or are services too frequent for that to be necessary?

The foot connections at places like Paddington are too tortuous for
anyone to claim that service A (from Abbey Wood) was ever planned to
connect with service B (west from Paddington on the main line).
