I see that the \expanded code has already been picked up in a branch 
there: https://github.com/texjporg/tex-jp-build/tree/expanded. So I'm 
guessing that is likely to happen.

At the moment what I'm aiming to do is get everything in one place so it 
can be reviewed, etc., and commented on. Particularly in the case of 
\expanded, the wider plan only works if there is general 
(pdfTeX/XeTeX/(u)pTeX) agreement on taking the patch.

Once we have that agreement, putting in pull requests, diffs, etc. 
against the 'right' places should be easy enough (at least in the sense 
I'm happy to sort it).

I don't imagine there is anything particularly controversial, but there 
is also the technical business (I'm no WEB expert).
