I think I=E2=80=99d like to see an evaluation of potential code-size =
increase that could impact more constrained platforms.

I don=E2=80=99t particularly care about code bloat on amd64 or aarch64 =
(I mean, I do, but the number of peolpe who don=E2=80=99t care greatly =
outnumber me and those are hills I=E2=80=99m not particularly interested =
in).  I do care about m68000 / m68k and vax and 32-bit sparc, though.  =
And I don=E2=80=99t think the skr1pt k1dd13s are targetig those.
