As a Roblox developer, it is currently impossible to understand who did a change of a package when there are many developers that has access, since there is no mention of who performed the publish anywhere.
If Roblox is able to address this issue, it would improve my development experience because we could have better control and give feedback to people who do unwanted changes to packages. It feels like a pretty basic feature to have in order to be able to work with packages properly.
This should preferably both be presented in the version history in Studio and on Roblox.com
