`public DateTime $date = NULL;` // this looks like the property is initialized

Much agreed. After instantiation, these shouldn't behave differently:
public $foo = null;
public Foo $foo = null;
Sure, method signatures have special behavior based on a default value, but IMO:
1. those semantics aren't entirely intuitive to begin with
2. property initializers aren't method sigs
3. the semantics would apply only to some properties
public DateTime? $date;
In C# the question mark after a type is a short hand for a generic Nullable
type.
I like that it's an established practice of doing exactly what we're trying to
do.
Could we not just make it obvious?:
public Foo|null $foo;
