There is no such requirement.

ELF supports having a read-only equivalent of .bss (type SHT_NOBITS, 
attributes SHF_ALLOC without SHF_WRITE).  We could allocate such a section 
name for read-only zero-initialized data and use it on ELF systems.  That 
way the data is read-only but doesn't consume space in the executable 
(presuming the rest of the toolchain handles this case OK).
