It's getting harder and harder to write an application that's 32-bit. Many dependencies these days are 64-bit only, e.g. TensorFlow. ANT is going to get left behind unless you commit to releasing 64-bit versions of the ANT libraries.
Personally, I'm looking at moving my app to 64-bit so I can use TensorFlow, which will mean dropping ANT support.
If you're not going to, or lack the developer resources, why not open-source and let us do it ourselves?
