This reminds me that there was actually an earlier proposal for an
"--ignore-missing" option -- in that case, to control GNU tar's behavior
when particular files were not found as the archive was being created:


I am not sure off hand if it would make sense to control behavior for
both create and extract using the same option or if they are different
enough in meaning that they should be requested separately. 

But in any case it seems the two requests taken together are an
indication that it would be useful to have a more structured way to
control what situations GNU tar treats as errors (i.e. causing it to
exit with an error status) and what is considered just a warning.
