Restrict Block from having a Parent or Ancenstor Block

I have a "custom/section" block with a template of "allowedBlocks" innerblocks eg. { children }.

But have been unable to restrict the "custom/section" block from having a Parent block.

I've tried the following settings in the "custom/section" block.json metadata.

{ "parent":[], "ancestor":[] }
//
{ "parent":[""], "ancestor":[""] }
//
{ "parent":["core/post-content"], "ancestor":["core/post-content"] }

This restricts insertion but does not restrict the block from being wrapped in a core/group via the editor ⋮ block settings.

Multiple instances of the "custom/section" block are allowed so contentOnly lock isn't appropriate.
