This is a very interesting point, because my experience is quite the opposite.
Most of the time changes to the apps that I typically worked on (ERP/CRM platforms) involved both DB migrations, as well as back end and front end work. And with the front end, changes to the logic almost always resulted in changes to the template, even if only within a single component. The only exceptions to this were validation changes (changed logic only) or visual bugs (changed template only).
I wonder what qualities of the system design this points towards, apart from coupling.
