But is there a fundamental difference in what people think of a footer or a footing based on what you call it?
Between "theming" and "placemaking" people end up with incorrect ideas about theme. Theme is not place, period, genre, etc... but because of the way the term theming has weaseled its way into the lexicon people associate "decorative elements which equate XYZ (period, place, genre, etc..)" that theme is as simple as that.
Which is a gross misunderstanding of the artform and reduces it to SoS and the idea that you spackle on "theming" to create a true theme park.
Think of it this way. Theme exists in many forms of expression/communication, but literature is one of the most easily accessible.
Now imagine if someone was writing a book and there was a suggestion they were 'theming it' by adding plotlines and foreshadowing and even verbs and adjectives!
That's patently absurd and misunderstands what it means.
