I seem to remember that there is some option in the customization
definition where some group will be folded into the surrounding list.
Ah yes, (info "(elisp) Splicing into Lists").

14.4.3 Splicing into Lists
--------------------------
The ‘:inline’ feature lets you splice a variable number of elements into
the middle of a ‘list’ or ‘vector’ customization type. You use it by
adding ‘:inline t’ to a type specification which is contained in a
‘list’ or ‘vector’ specification.
Normally, each entry in a ‘list’ or ‘vector’ type specification
describes a single element type. But when an entry contains ‘:inline
t’, the value it matches is merged directly into the containing
sequence. For example, if the entry matches a list with three elements,
those become three elements of the overall sequence. This is analogous
to ‘,@’ in a backquote construct (*note Backquote::).
