Reading the two rakaat nafl after witr

Q: My question is regarding the 2 rakaats after the witr salaah, what is the law regarding it? 

I have read in you fawta https://muftionline.co.za/node/33039 that our elders would read this salaah. However in ahsan ul fatwa, Hadrat Mufti saab explains this is not mustahab and also that no fiqh kitaab mentioned this. He also gave an answer for the hadith which shows these two rakaats after witr. 

What is the correct view in regards to these two rakaats?
