Not speaking for R-core, but the general answer to "could we include
this simple helper function in base R?" is "no, put it in a package or
in your own set of source()d helper functions; if it turns out to be
incredibly useful we might add it somewhere down the line".
You could ask to have it added to the `gtools` package, which has
been around for a while and has no strong dependencies ...

I often need to determine the span of the x-variable in a graphic.
This is easy to determine with:
diff(range(VAR, na.rm=T))
I am not aware of any function in base R that accomplishes this and “span” is
not taken.
Would it be possible to add such a function? Not a major addition but often
useful.
