The 1.0 API is deprecated (though not yet removed) in OpenUSD 26.xx releases. So it's time to migrate. Use of the HdSceneDelegate is mostly removed, except for retrieving the prims. Specific properties of prims are retrieved through schemas rather than querying the scene delegate. The full replacement of HdSceneDelegate is still ongoing in USD itself. In the very latest 26.05 only HdPrman has an experimental option for using the scene index directly, but for example HdStorm does not use it yet. So removing it's use with the current 25.08 in Blender is not expected to be stable enough. Additionally HdRenderer is supposed to replace HdRenderDelegate and its handling of tasks. However even in 26.05 that is only a stub implementation so there is no actual alternative to migrate to. Note that OpenUSD provides a compatibility layer so 1.0 and 2.0 hosts and render delegates can work together. Which means ideally everything keeps working the same, but there are likely some differences anyway. Support for OpenUSD version 23.xx and older was dropped.
