I do not have a strong opinion.  Either way sounds OK to me.
If you like, I can fix it up.


I think you mentioned LD_DEAD_CODE_DATA_ELIMINATION is under way for
ARM and x86.
If we can switch all architectures, lib.a will turn into built-in.o.  Correct?
(I am not sure how difficult the global conversion is.)




BTW, I saw abuse of lib.a in
https://patchwork.kernel.org/patch/9768439/

I see it in linux-next.

    clk: sunxi-ng: Move all clock types to a library




Now drivers/clk/sunxi-ng/lib.a
will go into thin archives.
The result might be different from what they expect...
