It's not really as bad as all that. The reason to avoid using those names is to avoid confusing the reader, not because it causes problems for R

  You can cause some mischief - if you write a package, or distribute a .Rprofile to colleagues, you can hide somewhere in there a temp <- F F <- T T <- temp and if your colleagues are lazy and use T and F (instead of TRUE and FALSE) fun and very gnarly to debug things are going to happen! Nichts ist wahr! Alles ist erlaubt!

    There are way worse things you can do than that! e.g. `(` <- function(x) { if (is.numeric(x) && runif(1) < 0.1) { x * 1.1 } else { x } } ;)

      That is beautiful, thank you very much! That's the kind of "bug" people don't even notice.
