This is indeed something configurable at the wanna-build level.

This is done on purpose in order to provide stable features over time.
If a package build-depends on foo | bar and foo is temporarily
uninstallable (for example due to a transition or a version mismatch
between arch:all and arch:any) bar will be used instead, possibly
disabling some features in the package. In the file & libseccomp
example, it means seccomp support might be silently disabled.

Note that for backports, alternatives are considered, as the above is
very unlikely to happen.
