Jon Sneyers, one of the developers of FLIF, since combined it with ideas from various lossy compression formats to create a successor called the Free Universal Image Format (FUIF), which itself was combined with Google’s PIK format to create JPEG XL. As a consequence, FLIF is no longer being developed.[1]
The format was initially announced publicly in September 2015,[6] with the first alpha release occurring about a month later, in October 2015.[2] The first stable version of FLIF was released in September 2016.[7]
So, not new and seemingly no longer developed separately from JXL.
iirc the main reason for QOI was to have a simple format because “complexity is slow”, so by stripping things that the author didn’t consider important the idea was the resulting image format would be quicker and smaller than something like PNG or WebP.
Not sure how well that held up in practice, a lot of that complexity is actually necessary for a lot of use cases (e.g. you need colour profiles unless you’re only ever dealing with sRGB), and I remember a bunch of low hanging fruit optimisations for PNG encoders at the time that improved encoding speed by quite a bit.

https://en.wikipedia.org/wiki/QOI_(image_format) seems interesting, though.
Qoi is good for some situations cause of its simplicity, but it’s not really the “best” at anything
