Builtin default of mmdebstrap is nice.

Various debootstrap wrappers exist which supports replacing debootstrap 
with an alternative command (e.g. cdebootstrap) but they commonly do not 
support passing arbitrary commandline arguments.

What I (and we, I guess) want is that the nice default be overridable, 
not only by passing options different from debootstrap but also in a way 
supported by these pre-existing debootstrap wrappers.

Example: Bootstrapping a system omitting security updates e.g. because 
an updated linux kernel is broken on my special setup.

Example: Bootstrapping a system additionally including backports.d.o.

Example: Bootstrapping a system additionally including my custom addons.
