Depends on you really.
I myself still have one in my system since i tend to chuck in a DVD from time to time, still have a few old school games on disc that require them to play/install and do find myself buying the odd physical copy of games if they are 1. Really massive, to save internet times/usage (GTA V for example, 70GB+) or 2. The physical copy has some appeal say the Witcher 3's which i got with the full soundtrack, map of the world and other cool features.
But this said, in general i don't add them to build recommendations by default, if someone knows they might need one i'm sure they can chuck one in for what $10 these days for a typical DVD drive. Hope this helps
