> tar/pax are kind of terrible formats. They are hard to implement correctly. I'm glad they are not used more often.

I'll grant you "kind of terrible", but what's hard to correctly implement about tar? It's just a bunch of files concatenated together with a tiny chunk of metadata stuck on the front of each.

Having never done it myself, I don't know, but I do know that the "microtar" library I picked up off GitHub is buggy when expanding GNU Tar archives but perfect when expanding its own archives. Correctly creating one valid archive is a lot easier than reliably extracting all valid archives. The code appeared competent, I assume tar just has a bunch of historical baggage that you can get wrong or fail to implement.
