it turns out this change breaks dask workloads :(. during my test runs, my dask workers were getting killed. and i found this in the logs:

OSError: /lib/aarch64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.32' not found (required by /opt/coiled/env/lib/python3.13/site-packages/llvmlite/binding/libllvmlite.so)
The above exception was the direct cause of the following exception:
