What youre pointing at is the trade off between concentration of understanding vs fragmented understanding across more people.

The former is always preferred in the context of product development but poses a key person risk. Apple in its current form is a representation of this - Steve did enough work to keep the company going for a decade after his death. Now its sort-of lost on where to go next. But on the flip side look at its market cap today vs 2000.
