The main disadvantage is the increased memory footprint which you
have to pay for a flexibility on the target which is usually not
necessary.
Your (a) is not really an argument; there are several solutions for
this "problem", for example:
genext2fs - ext2 filesystem generator for embedded systems
see http://packages.debian.org/unstable/admin/genext2fs.html
gBootRoot - distribution creation program which may be used by a normal
user
see http://gbootroot.sourceforge.net/
(b) is a matter of taste; for embedded systems, I tend to prefer a
fixed, static configuration which does not cost too much of the
resources which may be somewhat limited (espacially ROM and RAM).
Yes, MMV ;-)

By the way, ALL software projects are done by iterative prototyping.
Some companies call their prototypes "releases", that's all.
