Watson,

Sure, if people jump on standing up SLH-DSA TLS roots, and start using
SLH-DSA EEs for IoT use cases, then sure. But I believe that SLH-DSA has
other problems for IoT, like how the private key can be larger than
physical RAM on some small devices. So we'll see how much enthusiasm that
attracts.
