To what end? I think avoiding manual memory management is great, but I never had issues in Rust either, since I don't manage memory manually there either. I think that is kind of a point of Rust, as it avoids that whole class of bugs common in C programs.
But to what end do you want garbage collection (GC)? Just for having GC? Or a more specific purpose, that is difficult to attain with Rust's model?
For example: I usually want tail call optimization in languages I use. But not for it in itself, but for being able to write functions nicely, not having to worry about recursion depth, expressing things more declaratively, avoiding mutation (at least of an explicitly managed stack or any loop variable) and probably other things that don't come to mind right now.
The amount of time spent worrying about this is vastly overestimated. You don't really have to worry about lifetimes in your common day to day coding unless you're doing some seriously performant or low level stuff. At which point you probably don't want a GC anyway.
I’ve written a fair bit of Rust but it was ~5 years ago. I understand some ergonomics have improved but I think this somewhat depends on the type of application you are developing.
