I hope not. The repository is intended to share code, hopefully as
painlessly as possible, and currently (unfortunately) without any
guarantee that anything in it is necessarily R^nRS compliant. On the other
hand, I do try to spend the time on such conversions whenever I get a
chance, and that R^nRS-ness is one of the goals of the repository. I also
encourage those who have done such conversions to share their code, and
try to identify either a) implementation specificity or b) need for
conversion help.

I have no interest in wasting anybody's (nor my own) time, but, what would
you like me to do with something like "zebu" which has a selection of
non-standard C-scheme-isms? 

I think it is interesting and useful, so it is in the repository.

I have have included Kent Dybvig's extend-syntax stuff in the repository.
The file syntax.sha contains the MacScheme [posted] version [I think this
one is most up-to-date but please send me any fixes], the Dbyvig original,
and a MIT C-scheme version etc.

I would guess that any code using the es stuff will require the least amount
of work to adapt to the upcoming R4RS macros. [I say yeys!!hallelujah!! ;-)]
