Just be clearer in the documentation.

I will not stop asking for this, it is not specific to libavfilter: with
a quick search, I spot -map_channel that requires exactly the same
feature.

There may be filters that require an option to distinguish one channel
in particular; even if there are no now, there may be in the future. Can
you guarantee it does not and will not happen?

This use case happens at several places, therefore the parsing belongs
in a common API.
