Paddington to West Ruislip

I agree, but I'd have thought the same is true of Greenford West Junction to Old Oak Common West Junction (and will indeed be more so when Crossrail starts and paths on the inner GWML become scarcer)

Northolt to Greenford wont close, simple as.

Has anyone unpicked the HS2 documentation to understand exactly where these ventilation shafts are proposed to be? The OOC station box wouldn't affect Northolt to Greenford.

It won't close,however there a long list of separate signalling alterations to be briefed ov er the coming year.

The 'design refinements' consultation led to a report in 2013 that confirmed that the DfT were approving the tunnel, it includes this:

A small number of consultees were concerned that the location of the vent shafts might prevent future development of the Northolt rail corridor. HS2 Ltd will work with Network Rail to reduce as far as reasonably practicable the future impact on any likely developments of the corridor.

That's all I found, there doesn't seem to be detailed drawings immediately available...

I read that to mean the ventilation shafts might prevent double track being reinstated rather than they might cause the line to be closed.

Why, with a bit of thought, could a ventilation shaft not be designed so that a track could go across the top? Surely the airflow would not be greatly impeded if it was suitably sized.

Provided dump toilets have been abolished by then?

It's probably more complicated that that, especially as they may actually be "intervention shafts" with facilities for emergency service access and evacuation of stranded passengers.
