Documenting R's internal C API with roxygen2?


Just wondering if someone had thought of organising notes about the internal C API with an R package (roxygen2)? Or would that be too heretic?

In other words, something like Hadley's r-internals (GitHub - hadley/r-internals: Documentation for R's internal C API) but with the neatness of Rd pages in RStudio...

Glad to hear your opinion.
