If we assume it *is* for a second, the tradeoff here is "I need tooling to expose the type at the point where a variable is assigned" vs "I need tooling to help me change every call site if I change the return type of this function".
The capabilities of something are typically much more important than the concrete type. Hell often the type is either unnameable or unreasonably difficult to name. Features like async/await are making this even more common.

For code review -- why is the variable declaration site the place that we should force a type to be explicitly declared? It's just as likely for me to review a PR that adds `http://foo.do _thingy()`, why not force UFCS here for clarity?

My point wasn't so much that variables need to be declared at the point of use (I did say I didn't really agree with moxie here), but more that relying on tooling to solve these problems ignores the large class of situations where such tooling does not and likely never will exist
