I just tried it with Emacs's `master` and `C-h o seq-first RET` tells me:

    seq-first is a compiled Lisp function in ‘seq.el’.
    
    (seq-first SEQUENCE)
    
      Other relevant functions are documented in the sequence group.
      Probably introduced at or before Emacs version 27.1.
    
    Return the first element of SEQUENCE.
