I'm struggling to comprehend how a question I deliberately kept simple 
at just one sentence long can cause so much misinterpretation.

That just makes it historically wrong. Being incorrect for a long time 
isn't a reason not to fix it. Having two different keys to describe 
entities which come under the heading 'emergency services' is confusing 
to experienced OSMers let alone newbies.

As emergency=ambulance_station appears to be a later invention, was 
there a valid reason fire_station did follow suit?
