The other issue might be budget, again if the company is large budgets may be aligned to a spec or team location or hub. At this point in time a role might be 100% WFH but also for team f2f meetings/gatherings etc it might be more difficult to organise if WFH is across a large country instead of a city and its satellite towns.
OTOH, they might want you to read loads of them until you are blue in the face and see how unlikely it is :(
