I'd say it's a touch more insidious than that... Microsoft, Oracle, etc: they are highly motivated to present "demo-ware" solutions to half-interested devs to sell their languages (and related high-margin database licensing). This tends to be strictly use-case driven day-one issues that are designed to trick impressionable devs and project managers that these tools will address fundamental complexity. Oh look, a new "dynamic data" solution which optimizes a visible and annoying 0.002% of your project while locking you to a new untested stack... fun. People selling programming solutions to programmers have a lot of incentives to focus on the immediate problems of new projects. The stuff that kills your team/project/company don't start popping up until day 3.
