As mentioned in #6, the Git repository takes some time to clone due to the fact that the Git history contains old binaries for macOS and Windows (which have been removed from the code base in the meantime).

Investigation required

Is there a way to "compact" the repository, to avoid having to download a huge, unnecessary history? e.g.

• Maintenance and Data Recovery - Git Internals (official Git documentation)
• How to Shrink a Git Repository (Steve Lorek)
• Compact Git repository with history depth (StackOverflow)
• Compact repo by removing old commits (StackOverflow)
• Reduce git repository size (StackOverflow)
