R packages and not worry that one of them might accidentally delete
something important belonging to tlevine. I do the same thing for a Perl
program with lots of dependencies. And of course I do something like

applications? It is very easy to edit doas.conf and write wrappers,
but I would wrap far more programs this way if it were easy.
I know of many systems that create separate environments in separate
directories, such as Nix and pretty much every package manager specific
to a particular programming language (npm, &c.) but none that make
