Personally, I would not make git compulsory for developers of clients, and
I would just add/modify R code in Rcpp11 to download/update the clones and
include them in the client. I think it is simpler than setting up git
subtree, etc.

They can just update to a newer embedded Rcpp11. You can keep two Rcpp11
branches alive if you want, so that users can upgrade to a bug-fix version
without breaking the Rcpp11 API in their package.
