To condense and summarize:
Resolution: optiboot will use the "OS_main" attribute instead of
"naked." It doesn't disable the optimization, the resulting code is
"small enough", and the attribute is more exactly appropriate and
correct as well. It was probably an oversight that OS_main wasn't
used in the first place.
OS_task and OS_main are loitering around in official GCC sources quite
some time now, since October 2007 which is since 4.3.0.
The documentation was added 4 years later (PR49824) and is online since
4.6.2.
