The current documentation says:
| On older systems, the leading `-' can be replaced by `+' in the
| obsolete option syntax with the same meaning as in counts, and obsolete
| usage overrides normal usage when the two conflict. This obsolete
| behavior can be enabled or disabled with the `_POSIX2_VERSION'
| environment variable (*note Standards conformance::), but portable
| scripts should avoid commands whose behavior depends on this variable.
so basically it was disabled as it violated the required standards
compliant behaviour
