Does it matter? I don't think #line is particularly close, it is

Bad example - it impacts program semantics a lot.
Not if done properly. Why would it?

Same here. Such stuff is done by compiler-specific attributes
or pragmas. It has no similarities with stuff like #foldregion
and should not be treated same.
Pragmas and compiler-specific attributes suck and makes code less
readable. Inlining and unrolling is common enough to warrant
support, otherwise programmers will do manual unrolling in
inner-loops in order to get portable code.
