more a reversal of the default:

I see it as:
default is 'automagic=true' (more exactly 'not having --maintainer-mode')
and it do a best effort to build with what you have

that way a causal haker can do
and it does something sensible based on the environement.

if you want a speficifc distro-pattern use --with-distro= (which
whould disable the automagic things) (you can still override
individual by adding --with-xxx --enable-xxx etc.

if you want to pick exactly what you want: --maintainer-mode, with the
exhaustive list of everything that need choosing. (note: as a side
effect, when a new options show up, distro-profile will break... which
is a good thing, since distro maitainer should make a decision about
that new options... and that will certainly attract their attention
:-) )

LO dev can use --with-distro=LibreOfiiceDev, that will activate as
much thing as possible
