Follow-up Comment #1, bug #45701 (project avr-libc):

The current startup code allows a custom value for SP init by defining symbol 
__stack , for example:  -Wl,--defsym,__stack=0x123  or by defining that symbol
in a custom linker description file.

Moreover it is not uncommon to (re)start an application by jumping to 0x0,
e.g. from a bootloader.  If the startup code was "optimized" as proposed, that
code will no more work as expected.
