Flux and Metal circular dependencies in 1.10.7

Dearests,

I was inspecting my new MacBook pro M4 GPU capabilities. I created a TestMetal package on a fresh new environment in 1.10.7. I added Metal and Flux but received warnings that a circular dependency was detected.

(TestMetal) pkg> st
Project TestMetal v0.1.0
Status `~/SCRA/PKG/TestMetal/Project.toml`
  [587475ba] Flux
  [dde4c033] Metal

Then I instantiate the package
