`getFetchVersion()` could return null in two scenarios:
* The plugin didn't specify any constraints.
* The plugin specifies constraints and we fail to meet them.
It seems we really should be able to differentiate between these two
scenarios. For example:
* Should we only fall back on pinned version if the plugin doesn't define
constraints?
* If the plugin does define constraints and we fail to meet them, should we
display a warning that we're picking a plugin version that might not work?
