Although functional, the limited read/write memory is needless used to
redundantly store
static read-only initialization data/strings effectively eliminates this memory
from having
any useful purpose.

I assume you are talking about the following code:
/* __do_copy_data is only necessary if there is anything in .data section.
Does not use RAMPZ - crt*.o provides a replacement for 64K devices. */

And this fixme:
/* FIXME: output these only if there is anything in the .data / .bss
sections - some code size could be saved by not linking in the
initialization code from libgcc if one or both

Possibly (but likely of similar concern for other small embedded targets)
The problem is that the initialization data which is linked in .data (stored in
readable flash/rom)

Yes because MOVE_RATIO is too low for avr really. But there might different
issues here really, one is
for an example MOVE_RATIO is too low which causes the addition of the .data
