That would certainly be a possibility but it seems to me that this is
sufficiently simple to add to base R. If it is in a package, users would need
to install the package.
"Sufficiently simple" isn't a high priority criterion for base R
functions. "Useful but impossible for a user to write" is probably the
highest one.
If an R core member spent time adding this function, then they'd spend
less time adding things that nobody else can add.

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.
