By the same argument, you could say that we should keep completely
broken and wrong packages on the AUR, because there is a chance someone
will create the same broken package in the future again. The best thing
we can do is drop this stuff and do our best to prevent it from
happening again. There are even tools for automated detection of stuff
that is duplicated in the AUR (see aurdupes [1]), so I do not think it
is a big issue.

The provides directive makes sure that people can put something like

    depends=('xorriso')

in their PKGBUILDs and it will automatically use libisoburn instead --
basically what you are trying to imitate with those empty meta packages.
optdepends can be used for something like:

    optdepends=('tcl: for xorriso-tcltk')

I think the combination of these is what we want, isn't it?

You can check the PKGBUILD(5) man page for details. There is an online
version at [2].
