Should we still keep the build option and other infra around so that users can build from source if required? We just have to stop maintaining the packaging pipelines and pushing pkgs for this.

Yes, we can. But I worry it will be quickly out of maintain. For example, the #ifdefs for PrePack functions are subtle, they could be easily missed.

It's up to you. If you want to keep this change small, I can scope it down to just the yaml files.

Ok, then let's remove it. Things going out-of-date and having to answer support questions is not good.
