There may be negatives to this, but if you listen to any recent talks with Jack Dorsey, he is genuinely concerned about combating the amount of fake accounts on Twitter. Of course, it's both a moral issue and a business issue but that's beyond the point. If giving my phone number to Twitter means it can have an ever so slight positive impact on the amount of trolls and fake accounts on Twitter, then it's a good thing to me...

However, we have seen with Facebook that giving your phone number doesn't necessarily work in combating trolls, so I'd be interested in how exactly they will use it.
