Jonas Nick(@n1ckler):This is a fantastic idea. 4.2× faster SLH-DSA compatible signing while reducing the signature budget to 2^48. No verifier changes required. Or, if you prefer: ~500× faster key generation. Way more than just a hack. And a great writeup.

Attention hardware wallet devs, there's a hacky trick you can use to generate hash-based pubkeys and signatures WAY faster while maintaining compatibility. The catch: you can't create as many signatures.
