These details are now moved to the bottom of the help screen, below the
information that is immediately relevant.  Without a major re-design of
the help screen, I think that's as good as it gets for now:

    seq-map is a compiled Lisp function in ‘seq.el’.

    (seq-map FUNCTION SEQUENCE)

    Return the result of applying FUNCTION to each element of SEQUENCE.

      Other relevant functions are documented in the sequence group.



    This is a generic function.

    Implementations:

    #'(sequence sequence) in ‘seq.el’.

    Undocumented

    #'sequence in ‘seq.el’.

    Undocumented

I suggest closing this bug report as fixed in 28.1.
