You say that "This config is not supported (having a version of lldb which is more recent than the installed SDK)." but I'm not sure what that means and that definitely doesn't sound right. Is the problem that #144913 doesn't work with older versions of the SDK? If so, can we make it behave correctly with older and newer SDKs instead?

I brought this up with @adrian-prantl couple of weeks ago and the conclusion was that the green dragon AArch64 bots do run macOS 15. We would only lose coverage on the Intel bot that's running macOS 14. I don't think it's worth keeping support for older SDKs alive for this particular feature. It's currently in maintenance mode and the reason @charles-zablit is removing support for older SDKs is because it unblocks some performance work for LLDB on Windows. Which seems like on OK trade-off to me
