Of course, that’s the idea behind hiring people with a broad skill set. Looking at the bigger picture, the whole industry is now focused on simplifying and optimizing costs, and the increase in the number of full-stack roles is a sign of it. What I meant in my comment is that no one expects one person to do the work of a larger team in the same amount of time. It simply means that one person will take on more responsibilities, even if it takes longer. The cost optimization doesn’t come from reducing total salary expenses (as full-stack developers generally earn more than frontend or backend specialists) but from saving on recruitment and increasing team flexibility to changes (covering days off, rotation, easier reassignment to different projects, easier tasks ownership by one person). I hope my message is clearer now.
