Looking at a few examples it would appear that, in general, whether to map stations separately or not is somewhat arbitrary.
My own subjective views: * St Pancras (International) is one station serving Midland Main Line, International Services, Kent via HS1 and Thameslink. The Thameslink platforms have their own station node: https://www.openstreetmap.org/node/12254780537. A good analogy is Zurich Hbf which has a similar mix of a central main set of platforms with subsidiary groupings either side (but underground). * Paddington. Main Line, Hammersmith & City and Praed St stations are separate. I haven't travelled through it since the Elizabeth Line opened. Note the H&C platforms were (are?) included in the main line station numbering and at one stage were better integrated with the suburban line platforms. Note that the additional trxt (Hammersmith & City ... ) included in the names, and similarly at the two Edgware Road stations, whilst useful, is probably not correct. * Richmond & Ealing Broadway. Single stations. Tube & main line platforms have distinct branding and access though. *Liverpool Lime Street. I think of the Merseyrail platform as being a distinct station. Strong separate branding, it's own ticket office etc. However the station was built explicitly for interchange. I only discovered the direct lift connection in the last 15 years after using it since it opened. * Basel SBB & Basel/Bâle SNCF are mapped as separate station nodes ( https://www.openstreetmap.org/node/1900131629) although not apparent at first. About 20 years ago the difference was very apparent as the SNCF one had machines to validate tickets before boarding as well as a customs hall. * Tirano. The two minor stations are located next to each other, but mapped separately ( https://www.openstreetmap.org/relation/47003#map=19/46.215544/10.166924). Equivalent situations in the UK occur at Ravenglass ( https://www.openstreetmap.org/#map=18/54.355423/-3.408245) & Porthmadog (https://www.openstreetmap.org/#map=16/52.93112/-4.13335). At Blaenau Ffestiniog two station nodes exist, but I believe this is a jointly operated station (https://www.openstreetmap.org/node/1836862135, note, also incorrect wikipedia and wikidata tags). * Chur, Landquart : big interchange stations between SBB and RhB regional 1 metre gauge services are single nodes. Brig, a similar interchange is, however, 2 nodes. Tl;dr. There's not as much consistency as I expected, even for a single station such as St Pancras International. Even if in general, tube stations are mapped separately, but Ealing Broadway & others show perfectly sensible mapping where that is not the case.
