This is not a comment either way with regards to which runner to use. I will implement the ids/idt check on whatever platform is chosen. This is just an update as to where the ids workflow stands for both, before I go on leave for the next 2 weeks. I have managed to ids/idt to build on Linux. It takes around 2-3 minutes to build ids (see https://github.com/llvm/llvm-project/actions/runs/16962718956/job/48079138233).  I tested to see whether the Linux based workflow would detect if a PR had a missing LLVM_ABI by removing one from a class, and it didn't detect it, so something is wrong with the flags currently chosen.

Despite trying all day I am yet to get a successful Windows build of ids on either the Windows x86 or arm runners. If I do manage to get it to work, then it will likely take 5-10 for the build and check based on my progress so far.
