To me, the two major problems are:
- no namespaces
Someone uploads "serde2"? that's blocked forever. Someone uploads a typo version of a popular package? Too bad for you, learn how to type.
- the github connection
If you want to contribute to crates.io you're bound to github. No gitlab, codeberg, gitee, sourcehut, etc.
Not sure if there are any other problems, but those two seem like the biggest things and #1 is AFAIK not something they ever want to change + it would be difficult to as one would need a migration strategy.
While I don't want to deny the problems of not having namespaces, they will introduce a new set of problems. One issue with Github and similar platforms with namespaces is that a search for a repo turns up multiple projects with the same name under different namespaces. It's always a confusion as to which one is canonical. Another problem is that people are now going to name squat namespaces instead of project names. Imagine somebody registers the serde namespace. Their crates may be mistaken as the canonical one.
Isn't github used only as the auth provider? It is not using any git features, just leaning on the security guarantees of github. I don't find this too alarming.
If you want, you can use git links when declaring dependencies in Cargo.toml. So alternative to crates.io is basically any git host already!

Still makes you bound to github. Can't publish to crates.io without github.

What security guarantee does github have? I can create a new account right now with a random email, sign up for crates.io and type-squat a package.

Sure, but how do you discover the package? That's the other function of a registry. Also, I could easily just add another package as a submodule, but that's not the point.
For #2, there isn't anything stopping a separate auth system not through GitHub. Really just needs someone to own the implementation. See https://github.com/rust-lang/crates.io/issues/326#issuecomment-216662599 for past discussion surrounding this.
I don't understand the "serde2" issue. Isn't "someusername/serde" strictly worse than "serde2"?
GitHub being the only auth provider is something the maintainers wanted to fix, but didn't have enough bandwidth to implement. I think they would welcome contributions!
