To quote:
\defineBarLine "|:" #'(":||" "" "|:") % a)
\defineBarLine ":||" #'(":.." "" " ||") % b)
\new StaffGroup <<
\new Staff { a1 \bar "|:" a \bar "|:" }
\new Staff { f'1 f' }
>>
So he is defining a bar type "|:" himself. To further quote:
4) Would it make sens to have a fourth bar line situation (besides
in a line, end of line, start of line): The final bar line at the
very end of a staff?
With the "pure" approach of the barline interface this question should
not even be possible since _iff_ end of staff is to be treated
differently, the user is expected to pick a different bar type himself.

New bar line interface
* the input string of a bar line called by \bar "<bar string>" resembles the
* (define-bar-line ...) or \defineBarLine allows for new definitions. These
the bar line itself, the bar line used at the end of line, the bar line us
* Annotations for barlines can be added to distinguish between two identical
apperance or span bar lines.
* To align span bars properly, the space character " " has a
special meaning. When it occurs, the width of the resembling glyph in the
* New glyphs can be added easily.
* Volta brackets take the bar line dimensions into account.
and is not at all constrained to changing \bar "|:" to \bar ".|:". I
don't think we have a policy that features may only be removed
completely rather than fixed.

Not exactly an endorsement.
