There's definitely a need for a better system. Some would argue that we have package managers specifically to help solve this problem. Yet, for many developers who just want a "good enough" install system without thinking or working at it much, curl-and-exec gets the job done. That so many people aren't thinking about security at all is a sad comment on the state of software engineering. But perhaps inevitable, given our cultural history of favoring freedom over security.
