Warning message from 1.8.0-rc3

Hi, I’m getting

```
WARNING: could not import Base._rangestyle into ArrayLayouts
```

when I run CI for my package  [SIAMFANLEquations.jl](https://github.com/ctkelley/SIAMFANLEquations.jl) . This seems to come from BandedMatrices' dependence on ArrayLayouts. This is new for 1.8.0-rc3. 

Is this serious?
