I would like a StaffGroup without any systemStartDelimiter -- staves
grouped inside simultaneous music will not do because I would like a
\with clause to modify the context plugins. Unsetting the
systemStartDelimiter does the trick
\new StaffGroup \with { \unset systemStartDelimiter } <<
\new Staff { c''1 }
\new Staff { c''1 }
>>
... but not when when nested inside another StaffGroup
\new StaffGroup <<
\new Staff { c''1 }
\new StaffGroup \with { \unset systemStartDelimiter } <<
\new Staff { c''1 }
\new Staff { c''1 }
>>
>>
Removing the System_start_delimiter_engraver solves the issue, but maybe
there is something to improve here.
\new StaffGroup <<
\new Staff { c''1 }
\new StaffGroup \with { \remove System_start_delimiter_engraver } <<
\new Staff { c''1 }
\new Staff { c''1 }
>>
