Yes, indeed.  I agree, too.

In this particular case, yes, probably it should not.  But the problem
is more general than that.  Consider, for example, running

   tar --transform='s,/subdir/,/sub-dir/,' -x -f archive.tar

and suppose that archive.tar contains the following symlink:

   dir1/a -> ../subdir/a

The link target contains leading dots, but it is obviously subject to
filename transformation, otherwise the extraction won't be correct.
