I can see that argument, but what then? What should be the best
practice for a maintainer?
A new slot of a package (which doesn't exist today) may or may not
work with any ebuild in the system. Should it be considered a best
practice then to specify || deps with all slots that are known to work
in the tree? Or should we just trust to luck and consider it
acceptable for maintainers to add new slots of commonly-used libs and
users and downstream maintainers can deal with the resulting breakage?
Library maintainers don't seem to like dealing with that, so they just
stick new slots in an entirely new package, and then we end up with
all the || dependencies anyway and we make no use of the nice slot
syntax because it is prone to breakage.
It seems like the current way we handle slots for dependencies works
just fine until somebody actually tries to introduce a new slot for a
package, and then a whole pile of assumptions comes crashing down.
