I use the \postscript a lot when typesetting contemporary music e.g.
like this:
\version "2.20.0"
wave_line = \markup {
\with-dimensions #'(0 . 0) #'(0 . 0)
\postscript #"0.3 setlinewidth 1 setlinecap [0 1]
0 0 0 setrgbcolor 0.00 -3.50 moveto
0.23 -3.71 0.47 -3.93 1.00 -4.00 curveto
1.53 -4.07 2.36 -4.00 3.00 -3.50 curveto
3.64 -3.00 4.11 -2.07 4.50 -1.46 curveto
4.89 -0.84 5.22 -0.55 6.00 -0.80 curveto
6.78 -1.05 8.03 -1.83 9.00 -1.53 curveto
9.97 -1.23 10.66 0.15 11.50 0.50 curveto

}
This use case continues to be supported with
Cairo. Just convert \postscript to \path, wich
works both in the current PS backend and with Cairo.
\version "2.22.1"
wave_line = \markup {
\with-dimensions #'(0 . 0) #'(0 . 0)
\path #0.5
#'((moveto 0.00 -3.50)
(curveto 0.23 -3.71 0.47 -3.93 1.00 -4.00)
(curveto 1.53 -4.07 2.36 -4.00 3.00 -3.50)
(curveto 3.64 -3.00 4.11 -2.07 4.50 -1.46)
(curveto 4.89 -0.84 5.22 -0.55 6.00 -0.80)
(curveto 6.78 -1.05 8.03 -1.83 9.00 -1.53)
(curveto 9.97 -1.23 10.66 0.15 11.50 0.50)
(curveto 12.34 0.85 13.32 0.17 14.00 -0.50)
(curveto 14.68 -1.17 15.05 -1.84 16.00 -2.50)
(curveto 16.95 -3.16 18.47 -3.82 20.00 -4.49))
}
{ s1*5^\wave_line }
Actually, this is better in any case, because from
\path LilyPond is able to get extents and "skylines"
(outlines). Try:
\version "2.22.1"
#(ly:set-option 'debug-skylines)
wave_line = \markup
\path #0.5
#'((moveto 0.00 -3.50)
(curveto 0.23 -3.71 0.47 -3.93 1.00 -4.00)
(curveto 1.53 -4.07 2.36 -4.00 3.00 -3.50)
(curveto 3.64 -3.00 4.11 -2.07 4.50 -1.46)
(curveto 4.89 -0.84 5.22 -0.55 6.00 -0.80)
(curveto 6.78 -1.05 8.03 -1.83 9.00 -1.53)
(curveto 9.97 -1.23 10.66 0.15 11.50 0.50)
(curveto 12.34 0.85 13.32 0.17 14.00 -0.50)
(curveto 14.68 -1.17 15.05 -1.84 16.00 -2.50)
(curveto 16.95 -3.16 18.47 -3.82 20.00 -4.49))
{ s1*5^\wave_line }
versus
\version "2.22.1"
#(ly:set-option 'debug-skylines)
wave_line = \markup

Denemo uses postscript to generate a title page with a border.
From a glance at the output of
git grep "\\\\postscript"
in the Denemo repository, that should be easy to convert
to \path as above.
