Thanks for the review! That makes sense, I'll create a new branch before merging the PR. I think I'll hold this till coffea migrates to vector as the process has already changed several things in vector.

[Saransh-cpp]

Now that coffea has switched to vector and the changes are up in a release, it should be okay to merge this in. I will wait for a couple of weeks before merging this, just in case we get some suggestions from coffee users. I think pyhep.dev would be the perfect place to merge this in and create a new release.
