Overriding crates.io version for all crates

1 
#   Override egui - doesn't work.
[patch.crates-io]
wgpu = { version = "22.1" }

yields, as expected:

error: failed to resolve patches for `https://github.com/rust-lang/crates.io-index`
Caused by:
  patch for `wgpu` in `https://github.com/rust-lang/crates.io-index` points to the same source, but patches must point to different sources

This old issue indicates the problem. What I want to do is to force all crates in crates.io which reference wgpu to use version 22.1 from crates.io. One old crate is pulling in an old version of wgpu and causing type clashes. Is this even possible?

(Use case: the 3D graphics stack for Rust has many interdependent projects, which, right now, are out of sync.)

Cargo doesn't support this.

That's what I thought from a similar problem last year. I was hoping something had changed or there was a workaround. Apparently not.

Nope. It's one of the 4-digit bugs:
