I had a choice to make between
a) keeping Rcpp on CRAN
b) keeping that feature.
I chose a).
If someone needs b), patches are always welcome. It should not be
hard to
support conversion to character.
It wasn't the first time, and likely not the last time, that I had to
curtail
code of yours to make a release possible. Such is life.
You write a lot of great code, but some violates some CRAN guidelines
(which unfortunately change over time) and some break other things.
So
sometimes we do need to revert.
