Ah ok, I was assuming that having this be a fully transparent & reversible issue of representation isn't really possible - but if it is, then sure, then I'd agree, then it can be treated just like indentation or syntax highlighting color schemes. But for the major issues like split between "lots of small functions" vs "one big function" even if the IDE could e.g. inline the functions for readability, but that feels a bit risky as it makes it difficult to talk about the code or document a functions' interface if another person is seeing different semantic structure of the code, it's as if they had different names for the same things.
