Here comes a not-so-nice one: Sorry to be blunt, but I think the current
reality is that one's effectiveness in scientific computing is not likely to
be high if s/he can't read C for Fortran code.
The mode of development for new methods, I believe, should be:

If I do not know C or FORTRAN, how can I fully understand the package or
possibly improve it?

Thanks for all the nice discussions.
Though different users have various needs from R, It's always good to stand
on the shoulders of giants (as roger said). How far we will see depends our
ability to understand what have been done by other languages.
The package written in pure R might be
