"Use `Option[]` for optional parameters except collections" wanted

[plokhotnyuk]

Currently there are 3 options:

• Use Option[] for optional parameters
• Use Option[] for all parameters
• Do not use Option[]

Could you please add 4th one to avoid wrapping collections to Option[] for class fields because a lot of JSON parsers for Scala can handle missing values for them using empty collection instances.

That would be useful. Some(Seq.empty) and None often has the same meaning, so such duality introduces ambiguity in processing code.
