Fully agreed.

OTOH I had the same idea as Barry the other day about maybe making files like
$R_HOME/profile.site 'walk' over a directory, say, $R_HOME/profile.site.d/ so
that users could drop files there and upon installation and re-installation
those user-contributed snippets would just survive.  This foo.d/ directory
scheme is getting more and more common in Unix/Linux land as Barry noted.
