Colloquially, it just strikes me as language drift. Much like how people say “google” for any internet search, even though the word only really makes sense if you’re using that one company’s search engine.

Because it’s drifting like this, the definition for colloquial usage won’t necessarily be technical, they’re more slang usages. “Baking” probably becomes anything done in an oven. Roasting probably remains something cooked with high, dry heat.

So yes, some overlap if you dispense with technicality.
