Surely QR will want transit passengers more than ever(excluding obviously those 5 countries)
Yes, but I think it's more a case of how QR flights will be routed in and out of Doha given the surrounding airspace is controlled by Saudi, Egypt, UAE and Bahrain and will be closed to Qatari aircraft - and on top of existing restrictions overflying Iraq and Syria airspace.
Anyway, plenty of speculation and theories about that on the R&N and Middle East forums....
