No. We would hopefully go to great lengths to make sure that all
packages on AUR can be built and installed together. However, once
package FOO is installed, and linked to local versions of its
dependencies, there is not much we can do to prevent that an update to
FOO's dependencies breaks the *local* system if it's upgraded. In
other words, we can't automatically trigger a re-build&re-install of
FOO when its dependencies are upgraded.
Contrast this with the situation for binary packages, where we will
provide a re-built FOO when its dependencies receive updates.
