Many people would agree on the fact that we should be able to store
backend_layouts somewhere else than database.
Providing a simple hook is a way to allow this without fighting about TSconfig.

Back on the original topic, TSconfig could be a place to store
"default backend_layout", which will be loaded when no backend_layout
is selected. That means :
 * we can get rid off old layout code
 * we need only a few lines to build the virtual default
backend_layout from tsconfig
 * we need only a few lines of tsconfig to define that default behaviour
 * the default backend layout is configurable throught tsconfig
