I'm very okay with elif though because it makes it clear that the conditional is part of the chained block and not a brand new one.

The issue is that it's a special case that acknowledges where there are cases where the indentation level it logically requires isn't what programmers find pleasant, there are many more, that just don't have that special case, so it forces indentation that's unpleasant and unintuitive.
