In TeamCity 2018 I had some build configuration templates that defined their own clean-up rules. I've upgraded to 2021 and it looks like this was deprecated, though still partially supported for legacy reason. I'm fine with the deprecation and would like to not use a feature that TeamCity isn't keen on me using, but how do I now remove the clean-up from the templates? I can see the rules as being an inherited rule of the build configurations that implement that template, and I can see a way to edit that clean-up rule, but no way to remove it. Thoughts?
