I do that. But without the successful cache, I need to track all failures
manually because I cannot call 'urlcheck' again. To check the rest.

On the contrary. In general, if something was successful, then we don't do
it again unless there is a clear indication that the input has changed.
In all other cases an explicit 'drop' or 'clean' is needed.

For example, we don't skip the 'touch' for local_src/ links either. Even
though the code can change any time.
