they are just available in large sizes as the texbook makes it fairly
clear they are just there as an artefact of the construction of large
braces, placing the pieces together in different combinations.

You can also use ^|\lgroup| and ^|\rgroup|,
which are constructed from braces without the middle parts; and
^|\lmoustache| and ^|\rmoustache|, ^^{moustaches}
which give you the top and bottom halves of large braces. For example,
