Your comparison of fDate to DateTime is a good conversation starter. fDate was built precisely to provide such functionality as DateTime does, but it works in PHP 5.1. DateTime is only available in 5.1 if you explicitly enable it. fDate means you can use sane date handling on any version of PHP without worrying about what exact environment the code will be run on.

If you dig into Flourish for a bit, you'll find that Flourish is basically aimed at being a portable, secure base layer to build stuff on top of. It gives you a platform to work in PHP one layer above the PHP functions that are largely derived from C libraries. It includes stuff like UTF-8 string functions, input filtering, arbitrary precision math and whole bunch of other stuff that will work with any kind of (semi-popular) DB on any platform with any version of PHP 5.1+.

Because of this, it isn't going to use PSR-0, or namespaces, or other new language features in PHP 5.3+. However, due to the architecture, you can successfully use it with PHP 5.3 or 5.4 and use all of the new language features in your part of the code. However, when you need to actually send a standards-compliant email with an attachment including UTF-8 content and inline images in the HTML version, fEmail has your back. Oh, and it prevents email header injection along the way. :-)
