Is there a workaround for this?  
Is there a backward-compatible configuration in version 25 or higher that would allow USD files to be exported and used in legacy versions?

> Hi all, In working with the AOUSD’s core Spec group and TAC, and Pixar’s desire to retire some (quite old now) technical debt, we’d like to adopt the following policy - please holler if you have concerns! Moving forward, crate version 0.8.0 (the introduction of list-editable payloads) will be the minimum supported version, for both OpenUSD and the forthcoming USD spec. Version 0.8.0 will be (as of the next release) the default version authored to crate files, bumped up automatically per-file …

> OpenUSD v25.05 sets the minimum crate version and default version for new USDC files to 0.8.0, to increase compatibility with older versions of OpenUSD. Documents will automatically upgrade to newer Crate versions upon saving when using features introduced after 0.8.0, such as animation splines and path expressions..

> Support for versions of Crate prior to 0.8 are being deprecated, and it is recommended to update any older assets prior to the removal in future versions of OpenUSD. [usdcat](https://openusd.org/release/toolset.html#usdcat) can be used to re-export crate files to automatically version them up.

Thank you very much, Aaron!

I’ll be using USD ASCII as a workaround for the next couple of days, until our team finishes the update.
