1. What is the use case for this? Even If we customize it and restrict Author to create more pages under that path because that will not be displayed on the page which has List (V1) component, Author may want to create more pages despite this limit
2. If the List (V1) component is used on more than 1 page for the same path with different Max number set, which number to be considered
3. If really want to restrict Author to create more than X number of page better we can set some property at Node level rather than considering this MaxNumber property from one/few particular pages.
