Playground

[lcddh]

fn (f Foo) get(param ?int) ?int {
	return param or { f.age? }
}

Adding ? to the end of f.age seems to work.

Yes, but it must throws error without unwrapping the option.

[lcddh]

f.age is supposed to be of type ?int, so it should be able to return directly

f.age is supposed to be of type ?int, so it should be able to return directly

Not exactly. or block must resolve to unwrapped expected type, not to another option one. This is as V planned it.
