No.  It means that extraneous destination files are deleted regardless
of --*-size rules.  Protecting destination files that don't match the
--*-size rules from deletion might be desirable if rsync is run both
ways between a pair of directories, as discussed in bug 4378.

The above text describes a size limit that behaves as a hide without a
protect.  This would be covered under the generalized bug 4378.

This requirement cannot be reconciled with the others under rsync's
current design.  A hide would omit the large source file from the file
list, and then the receiving side would be unable to do the --update
comparison.
