This can be very useful! Thanks! Regarding the API, since this is pretty non-standard for the python library, perhaps a better approach would be to allow the user to pass their ownfetch function instead of only allowing them to pass options? This could be useful for loading models from custom filesystems too.

In fact, I think this would be better at theenv level. something likeenv.fetch = ...

You're right, I need some time to revisit it.

I added a custom fetch method, but after some thought, I realized that I still need to pass request_options as I do currently. Otherwise, every time an AbortController is used, I would need to reset env.customFetch, and there would be no way to cancel only specific fetches.
