But I am not aware that IMD per se may be illegal unless this causes splattering beyond limits. And I am not convinced that using a ham transceiver, maybe except for the latest Icoms, may be enough to have good IMD TX audio. Listening to HF sometimes you hear really distorted modulations and I don't think they all are produced by uBitxs. Having said this about a cleaner TX audio from the uBitx is always welcome.

I think that old protocol, as well as Pactor II, is currently used to send winlink emails over HF by hams for civil defence purposes.
