We found no usages of it in the wild. If there is real-world need for them, we'll consider adding them back.

FWIW I use binary literals a bunch in python, either when working with binary file formats or with bitfields.

Yes, I'm not saying there aren't usages for them in general, but PureScript currently occupies a niche that doesn't get down to the level of binary file formats. This change is more about "only supporting what we need to right now", rather than "we don't like binary literals". As noted elsewhere, it's not difficult to add support for them when we need to.
