Can I [easily] change the output of commands like \showlayout to show
dimensions in bp/dd rather than pt?

As a traditionalist I try to stick to dd/cc standard. For compatibility
with others I sometimes have to use bp standard. I find TeX native
standard of pt useless and very confusing. I would be happy to never see
those pts around any more. Is that possible with ConTeXt?
