I think this report simply reads too much into the name of a node.  A
node's name is a label, and needs to satisfy several requirements, so
it isn't always as accurate as the section name.

I don't think we need to do anything about this issue.  There's no
real problem here.  There are several index entries leading to this
node that readers could use, and the assumption that someone might
look up this node by its name, or be surprised that only defcustoms
are described there, is misguided, IMO.
