Move towards stability #4
Description
Currently, GATs and Pointer Metadata are the two biggest nightly features we need.
GATs are planned to stabilize in the not-too-distant future. This is a major step towards the crate compiling on stable, and will allow removing the GAT feature. Would like to have them stable before the next big release.
Relevant PR: rust-lang/rust#96709
Pointer Metadata has proposals to stabilize some types, but looks to still be a while off. This won't block the next release, but I intend to keep an eye on any movement in this area.
