Wait, why @maleadt ? What are we supposed to use here instead in v1.8?

[maleadt]

LinearAlgebra.QR. See JuliaLang/julia#42594 for JuliaGPU/CUDA.jl#1449 replacing JuliaGPU/CUDA.jl#1194 to fix JuliaGPU/CUDA.jl#1193. This whole change was because you requested support for more factorizations, so I'm surprised about you being surprised 😛

Oh I see. Yes, then https://github.com/SciML/LinearSolve.jl/pull/130/files#diff-4c8f9e26491b28a6897e9cf2c7f8d59c2f4c9b5fc66e1067a4d4fd8e3fd98226 solves this issue because enough has been upstreamed that we don't need to carry around those overloads. I forgot everything got upstreamed 😅
