I don’t even prefer it for indicating that something can return null. In most cases the Option API is more tedious and awkward than a null check and there are existing annotations that can be used to flag nullable return types, for documentation. The only places I’ve found Option to be helpful are where it helps with method composability, or in some hashmaps as a simple way to distinguish between “lookup not previously tried” vs “lookup resulted in no value” vs “lookup resulted in value” - it’s a hack and looked down upon because the Option value itself is null, but I view it the same as “Boolean” being nullable. As long as the details are encapsulated it’s not too problematic.
