Currently, the `else` branch belongs to the `if`; with your
proposal, it would belong to the `while`.
An `else` always attaches to the closest construct where it can
be accepted; AFAICS, this cannot be changed without making the
language grammar context-sensitive (it would require parsing
`while` inside an `if` differently from other `while`s).
Compiler have simplification of CFG passes that makes this
feature irrelevant in practice.
