Yes.

Relatedly, we need to think about the incentives these defaults
create.  Personally, I want *more* naive users to be building from
source, because then they are better able to test recent versions,
bisect, test my patches, etc.

As I hinted in my earlier reply, I think it would be best to try some
basic things to make DEVELOPER more visible first.  If that fails,
then we can revisit how to make this more drastic change in a way that
minimizes the harm (and I am not sure yet that that is possible).

Thanks,
