gitconfig was the approved interface reference name and is what was granted in the store. ‘git’ does not convey the same meaning when one does snap [dis]connect gitl:git which is why we require ‘gitconfig’. Please adjust this back to the agreed to name and [this portion of] the snap will pass automated review.
As for ‘gitl’, this is for $HOME/.gitl_history, but there doesn’t seem to be a reason why this file needs to be in this location and not the usual $SNAP_USER_DATA (aka $HOME). History files are typical only read and written to by the tool using them, not the user.
