GIMP doesn't run on embedded systems AFAIK (mainly because of its
minimum screen resolution requirements.)
In any case, what you said above is true and unrelated.  GEGL seems a
much better choice for batch manip generally, however even if you
would use GIMP, nothing would force you to use high bitdepths..  GEGL
allows you to make different versions of an operation for different
data types / colorspaces, so you would perhaps need to make
8bit-optimized versions (more likely, GIMP would implement these
itself already, since it's a common data type). The difference is that
GIMP needn't make that assumption, and thus the overall application is
more flexible, accommodating different color spaces and color depths
in the one application transparently.

In short: optimization reflects an underlying assumption, and the
assumption that 8bit is the only efficient choice is no longer true,
therefore the optimization of assuming 8bit is no longer appropriate.
