Wouldn't it be sufficient to write
\override Hairpin.to-barline =
#(lambda (grob)
(let* ((right-bound (ly:spanner-bound grob RIGHT))
(nhds (ly:grob-object right-bound 'note-heads)))
(not (ly:grob-array? nhds))))
here? After all, the original value of to-barline is not being accessed
at all. Though possibly this would need
\override Hairpin.to-barline =
#(ly:make-unpure-pure-container
(lambda (grob)
(let* ((right-bound (ly:spanner-bound grob RIGHT))
(nhds (ly:grob-object right-bound 'note-heads)))
(not (ly:grob-array? nhds)))))
to deal with hairpins broken across lines?
