No problem with platform as way (line) but as closed way, really.
Wonder about platform building a "ring" but no area. All the the ones I
know at least have different ref=* and therefore need to be splitted.

Could you show us a real world example, please ?

Same problem as highway=*, you never know if a closed way tagged with
aeroway=taxiway is an area or a loop.

As far as I can judge a clean separation would be the best:

for highway and aeroway representing the area as area:highway=*
respectively area:aeroway=* and only tag ways with highway and aeroway.
