Couldn't the vst3 export be replaced by DPF's Travesty custom vst3 implementation?

I noticed while reading the documentation that nih-plug relies on the official vst3 API for vst3 support which binds it to the terms of the gpl license when using the vst3 api.
There however is a publicly available ISC licensed version of the vst3 api named travesty that was made for the DPF project, they also have a vst2 sdk
https://github.com/DISTRHO/DPF/tree/main/distrho/src/travesty
https://github.com/DISTRHO/DPF/tree/main/distrho/src/xaymar-vst2 (vst 2 doesn't seem to use ISC specifically but the terms are similar)

I think those could be useful for the project
