What was the use case for auto that got in into the language?
In code where the type of the initializer would change, and if the type of the variable was fixed, then there would be an unintended implicit conversion. The other use case was voldemort types. Such patterns are commonplace, and a source of error and inconvenience without auto. auto appears in various forms in other languages, and is almost universally lauded as worthwhile.
These cases don't apply to this proposal, nor do I know of its successful adoption in another language.
It's not a matter of finding reasons not to implement it. It's finding reasons TO implement it. Language features do not have zero cost - some benefit has to offset it.
