Yes, it is not _inherently_ a bad thing, but I would say that it is _generally_ a bad thing. Sure, if you are raising a Series C and everything is about optimizing the hell out of your product, there might not be a place for generalists.
However, I would claim that if you throw out generalists, you throw out some of the core/most valuable people who could help the company establish new products and help you grow into a multi-product company (diversifying your portfolio is generally a good thing). If the company is only left with specialists it will slowly transform into another one of those industry giants that struggle with innovation.
