In a lot of cases, it's less that developers are afraid of light sysadmin tasks and more that companies don't employ anyone capable of development, outsource it to agencies, and then end the relationship once the project is complete. If the devs deploy it to Vercel or Netlify or similar, they can be reasonably certain it will run as-is for months and probably years with no intervention because they client won't be willing to spend money on maintenance. That makes their client happy and leads to repeat business later down the line when budgets allow. Tech debt and lack of proper maintenance is a significant concern with agency projects and is why companies like Vercel and Wordpress hosts like WP Engine are able to spin up and grow so quickly.
