It wouldn't be that much of a performance hit.  Rather than fetching the
directory with a normal gopher request, then fetching the attributes for
each entry of the directory, the robot could make a request something
like this:

        1/directoryF$+VIEWS+ABSTRACT+ROBOTS

which would fetch only the VIEWS, ABSTRACT, and ROBOTS attributes of
every item in the directory (in addition to the INFO attribute, which
contains the usual Gopher directory entry).  A fully Gopher+ supporting
robot would need to get the VIEWS and ABSTRACT to build a complete index
anyway.
