Is it?
Because according to https://www.freepascal.org/docs-html/ref/refse24.html
Managed types are an exception to this rule: Managed types are always
initialized: in general this means setting the reference count to
zero, or setting the pointer value of the type to Nil.
It is documented, which makes it a documented feature?
Also https://www.freepascal.org/docs-html/ref/refse20.html#x50-680003.9
states explicitly that they are initialized to nil (and there is no
restriction that local var are exempt from that).
