This probably goes in conflict with #899 (also in conflict with main apparently)

At the end of the JupyterLite workshop last week there were some brief discussions with @fcollonval and @hbcarlos about whether it would be worth updating JupyterLite to JupyterLab 3.6.

Since 3.6 mostly brings improvements to RTC, it can also be fine to stick to 3.5 in lite for now since https://github.com/jupyterlite/jupyterlab-webrtc-docprovider still works ok.

And focus efforts on updating to lab 4 and nb 7 directly: #826

Although it's still in draft for now, there is a chance the RTC frontend implementation will be making use of an IDrive: jupyterlab/jupyterlab#13512. This is still in discussion and not merged, but is looking like a simpler approach of enabling RTC in JupyterLab in general. JupyterLite would also benefit from it via the jupyterlab-webrtc-docprovider extension (which can be renamed later if needed) since this would mostly be encapsulated in a IDrive implementation.

@fcollonval @hbcarlos feel free to add more insights and details here if needed, or in #826.

I fully agree with @jtpio

With the nice drive approach targeting 4 and as our resources are sparse, I advice to skip touching https://github.com/jupyterlite/jupyterlab-webrtc-docprovider before 4. Hence this implies not upgrading JupyterLite to 3.6.

This works for me! I guess it will then be relevant to continue getting upstream bugfixen to a 3.5.x branch, as well for a while, then... we can't be the only downstream that will be unable to quickly shift and throw a bunch of resources at the new ydoc-related upgrades when 4.x and notebook 7.x, which will require many other changes, are coming Real Soon Now ™️ .

Closing in favor of #1019 as we'll skip the update to JupyterLab 3.6.
