[Discussion] Corner flags and markings

Proposition:

Add corner flags and markings at next major rule update (2023 or 2024)

Context:

From 2010 to 2015, several additional markings for localization were removed from the field design. But one element which is present in FIFA rules and not present in our rules is the presence of corner flags. With the size of fields increasing and the presence of corners in the rules, it might be interesting to add them on the fields.

The main reason for not having corner flags might be the price, however, given the cost of artificial turf for a field, it seems negligible.
