I was thinking this would be mostly about
non-breaking changes, such as those patches people are already applying manually and running in production.
disagree - breaking change
disagree - breaking change (people must rewrite their code to expect the RPC server to appear

That's more like it

I think this sort of change -- presuming it doesn't break any existing APIs, which I don't think it does -- would be perfect for these "useful patches" nightly builds.
Maybe you could setup a Bitcoin cloud build service? I login... add my branch and click generate builds.
Sounds like a great bitcoin business or website for somebody...
