Using this version, it will already be possible to "delete" (sub)menus from inherited structures, using the visibility="delete" tag on an item.

(legacy) remove javascript autoloading, all occurrences of it where replaced except the index/dashboard handling.

The file is probably not XML at this point.
Leaving this for @adschellevis.

Wouldn't it be better to do this unconditionally if more CSC
features are pushed and this might be missed again?
