I don't agree with this. We should not throw "random things" in there

because that will affect the possibility that Andrea's customization

can be composed with Joe Doe's, whose contribution I would also

welcome. If we follow your plan, it seems very likely that a sub-battle

for defaults emerges within it. So, no to "random". Only things that

our "custom-theme" infrastructure knows how to handle. If it doesn't

handle some of those, then either that infrastructure or a package's

custom.el conformance should be augmented.
