> *DefaultFilenamePolicy.ParamsCoder* uses simple *StringUtf8Coder* for encoding/decoding *DefaultFilenamePolicy.Params*'s *baseFilename* and therefore looses information whether *Params.baseFilename* resource ID is file or directory.
> The result is that it's effectively preventing user to define directory as *baseFilename provider* when using dynamic destinations because after deserialization it's translated to file.
> Solution is easy - use *ResourceIdCoder* for encoding/decoding.
