I would presume it is the same as for extensions, which is
described in registry note as:

"If an item is not marked as 'Recommended', it does not necessarily mean
that it is flawed; rather, it indicates that the item either has not
been through the IETF consensus process, has limited applicability, or
is intended only for specific use cases."
