Sure, the default shouldn't be altered.

What would be ideal is the ability to alter the default for a particular
scope:

void __attribute__ ( (__section__ (".some_section")),
                     (__strings__(".some_string_section")))
foo(void)
{
	bar("hello");
}

So during the scope of the __strings__ attribute, the old (".rodata")
section identifier is stacked and replaced with ".some_string_section".

Guess I should shut up and look at the source :)

mm..  A "few dozen kb" is fairly attractive, actually.
