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

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