I think of it more as that Python deigns to permit semicolons.

Hell no, considering that the sizable majority of lines *aren't*
split, which makes those semicolons completely redundant to their
accompanying newlines. We'd be practicing poor Huffman coding by
optimizing for the *un*common case. It would also add punctuational
noise to what is otherwise an amazingly clean and readable syntax.
Accidental semicolon omission is (IMO) the most irritating source of
syntax (and, inadvertently, sometimes other more serious) errors in
curly-braced programming languages.

Such a core syntax feature is not going to be changed lightly (or likely ever).
