> Fixing GET would be easier.

I disagree. I think the adoption (or dismissal) of QUERY will show.

First thing that comes to mind is that the idempotency of GET resources are easy to handle. URL's have a fixed size, they can be efficiently hashed, cached and are unambiguous about how they serve this purpose.

It is unclear how the ecosystem will deal with the QUERY requirements. It's easy for apps, but browsers, http caches and servers will take some time to figure out solutions.

Fixing GET would have the same amount of uncertainty in addition to the need to keep current expectations valid. It's not easier, it's harder.

Browsers won't.

No, really, they simply won't implement it.
