It is still present in 2.27.2. Follow the provided link...

I'd recommend the first.
extra-dy will always be 0.75 or -0.75
You'll need to find the needed value for
Glissando.bound-details.right.Y by try and error, though.
You may want to create a function for it:

glissToBar =
#(define-event-function (dir y-off mus)(ly:dir? number? ly:music?)
#{
  \tweak to-barline ##t
  \tweak extra-dy #(* dir 0.75)
  \tweak bound-details.right.Y #y-off
  $mus
#})

\new TabStaff
{
   g'1\glissToBar #DOWN #3.75 \glissando f'
   f'-\glissToBar #UP #3.75 \glissando g'
   c'-\glissToBar #UP #2.25 \glissando d'
}

You may differ, though ;)
