The proposed functionality is useful (I've encountered situation
described by Thomas),
but IMO this will add some confusion.
Most people would just use depends even for run-time-only depends
(when they're not cirlular, of course),
so rundepends would be used only to workaround those circular builddepends.

What I did to workaround the situation described by Thomas:
* build A without depends=(B)
* add depends=(B) and repackage with makepkg -R
