Sorry I meant to open this on my fork but somehow it opened upstream. Let me close this if CI fails

[mathetake]

looks like it's working hah

[mathetake]

well maybe it's already cached... could you try changing the cache key for testing?

[anuraaga]

@mathetake There's lots of output like this. Do you think it's still needed to verify with different cache?

Well why not, giving it a try with different cache key
