Now that the full bindless mode has been stripped (#710), I would like to open up this issue so that we can all get on the same page and see if we can support the Traverse use case as well. I'd like to inquire about near-term steps forward when it comes to bindless.

• What are the plans for the equivalent of bindless ByteAddressBuffers going forward?
• What is the current trajectory for specifying bindings as globals in rust-gpu?

In the remove code there was a bunch of stuff supporting the equivalent of ByteAddressBuffer/RWByteAddressBuffer (meaning, no the buffer type gets decided in Load and multiple datastructures can be loaded from the same buffer at same / different offsets).

If there are no plans for this near term, could we look at reverting the code-removal while we get a plan together? Currently we'll have to straddle behind releases or fork the project which is really unfortunate.

Start by reviewing the bindless-mode removal in issue #710 and the remaining support for buffer loading through Load. Compare the requested ByteAddressBuffer/RWByteAddressBuffer behavior with the current approach to global bindings. Done means an agreed near-term direction or implementation plan for the Traverse use case; no file or test is named here.
