Do you think we should implement a special is_min/is_max since these are pervasive and used also for statistics ?

It might make sense to special case is_min and is_max
What we did in the case of ScalarUDFs was to go with functions that described the property in question was rather than what the function was. So for example, for coalesce and some array functions which needed special case type coercion rules, @jayzhan211 added a way to provide user defined coercion rules, rather than a is_coalesce function
I was thinking we would do something similar in this case. However, it if turns out that all such properties are only relevant for min/max maybe having a is_min / is_max API would be better than enumerating all the properties
