question: do we need manylinux_2_28_x86_64:2025.09.19-1 explicitly or would it be ok to use just manylinux_2_28_x86_64?

I pinned it to version cibuildwheel uses. The pinning is mostly so that we won't have silent or hard to trace failures. If latest image updates to a newer toolchain with ABI changes, it could error llvmlite builds or silently break numba builds.

numba-hatchery uses this too: https://github.com/numba/numba-hatchery/blob/main/compile.sh#L50

Yes, I actually got it from there. The python container image we use there has similar newer GLIBC and is ABI-incompatible to GLIBC on manylinux2014 image which was used to build llvmdev.
