Using .onUnload to unload DLLs

I've noticed that many of the "base" R packages have an .onUnload() function which automatically unloads compiled shared libraries with library.dynam.unload(). For example:
stats:::.onUnload
function (libpath)
library.dynam.unload("stats", libpath)
<bytecode: 0x1033b9c30>
<environment: namespace:stats>
I've noticed that many other packages don't do this. Is it considered good
practice to do this in packages that have compiled code?
Yes, but do not all packages have well-enough written DSOs to do this. (Tcl/Tk does not, so we no longer attempt to upload tcltk.dll.)
