Some suggestions for core:

  * remove-if / delete-if / remove-if-not / delete-if-not
     (_without_ the CL keyword arguments)

    [These are very handy for filtering lists of values.  The keyword
     arguments are not very important, and keywordless core versions
     would be compatible with keyword-supporting cl.el versions in the
     same way that core `dolist' is compatible with cl.el `dolist']

  * mapcan

    [Useful for mapping when there isn't a 1-1 relationship between
    argument list elements and result list elements]

  * multiple-argument mapping (mapcar, mapc, etc) functions

    [Useful and obvious generalization of existing mapping functions;
     Gnus already contains its own implementation of a multiple-argument

[I think all of these are simple and practical.]
