If the target is a gdbserver, then it would need to read the bytes
from the executable file.  This is easy to do with BFD, but if I
remember right, gdbserver doesn't use BFD at the moment; not sure how
to get around that.

If the target is an embedded system, then presumably the transparent
data ranges correspond to ROM regions, so the data is still there.
