You mean Rails and not Ruby.
I'd agree that, in the ruby community in general, or at least the English-speaking ruby community, general cultural values seem to be "dev early, release early, security hole early". Valuing innovation and release-often over stability/reliability. There are certainly some projects/developers that go against this cultural norm, but we are certainly not the first to recognize it as a general cultural norm in rubydom (and it's got benefits as well as disadvantages).
Secure is not cool, nor magic enough, it seems.
