It's more than "coders who don't know how to code", it's also managers who don't know how to read code or review diffs. Sadly, there are lots of experienced coders whose planning horizon stops as soon as the code works i.e., they don't maintain code or think in those terms as long as it's working. This is often why shops use these overreaching frameworks.

Systems administration is no different, which is why so many servers are now either straight-jacketed in OS packages + chef/puppet/ansible or such a mess they're the equivalent of spaghetti code.

IMO this is fundamentally a failure of higher education (EE/CS, IS ...).
