Not that I know of, but I don't think it's time yet.
They're non-build uses for pyproject.toml, so if build-backend isn't present, it just means that it isn't used for build reasons.
The pep517 package (python3-pep517) can validate metadata generated based on pyproject.toml, but it spins up it's own environment using pip and does a package sdist build to do so. I don't think that's what you have in mind.
In the pybuild plugin I did for flit, I do check for the correct build-backend when autodetecting if the plugin should be used. Using python3-toml it's a one liner. If we really want to head down rlthe path of checking, it ought to be simple enough to write.
