IMHO, for an OSS project, the line between "user" and "developer" tend to be
very fuzzy. Many contributions to the code came from people who *are*
users. They added features or fixed bugs because they want/need to for
themselves, and feel it might be useful for others.
No one can/will stop you from modifying the behavior of "[" for character
vectors in R for your own use. Whether your modification will be accepted
by the R community at large is an entirely different matter.

My vote is for this to be called a bug. The S behavior is consistent. R

And what do you think all those who put their time and effort into
writing/fixing/maintaining R are doing? AFAIK not a single one of them gets
a penny for the work they put into R.
