GPU based Image registration with itk-wasm

I have a question about WASM and GPU. On the web, JavaScript is currently the primary means of interacting with the GPU, I believe. Therefore, JavaScript should inject functions into WASM in order to achieve this. Am I right?

Does itk-wasm support porting the GPU methods in ITK? I'm mainly interested in GPU based image registration. For instance this one [GPUDemonsRegistrationFilter](https://itk.org/Doxygen/html/classitk_1_1GPUDemonsRegistrationFilter.html)

And lastly, do you happen to know any other ITK non-linear GPU based image registration methods? gpu based rigid or affine
