Hmm, I don't think so. It looks like `skimage.io._plugins.plugin.call`
looks in `skimage.io.plugin_store`. But `plugin_store` is populated by the
first installed plugin in a list of preferred
plugins<https://github.com/scikits-image/scikits-image/blob/master/skimage/io/__init__.py#L13>.
Whatever matches, takes over all io operations (more or less). If that
plugin doesn't provide `imread_collection`, then that entry in
`plugin_store` remains empty. (In other words, after accepting a
plugin, there's no additional check afterwards to fill in the functions not
provided by that plugin.)

Is there any reason why there's no default `imread_collection` which just
passes arguments to `ImageCollection`?
