I can see that all attributes from generated classes are optionnal. Is it by default ?

In some of companies i worked for, we agreed on swagger instead of json, it's way more efficient 😉 (jni do the trick too i suppose)

I'm also wondering if this is really time saving... I mean, if it saves me 5 minuts every months, it's less interresting than something saving me 30 seconds on a repetitive task. In my case, it may be more related to comfort than time saving 😂
