Well, the Varianter API[1] can receive variants from anywhere. Each
variant will carry the parameters that will be exposed for a test to
consume.
Yes, right now the only one[2] sending variants to the Varianter API
is the yaml_to_mux plugin.
It would be easy to create a "simple parameter interface", closer to
the core package, that would create one variant will all the
parameters you want, i.e. from the command line. But someone has to
write that internal plugin :)
