I think the two reasons for using tar were to preserve executable file
bits and to preserve symlinks. Funny enough, tar.exe doesn't do either
properly.

I looked through the commandline options that 7za supports and saw
nothing for file attributes or symlinks. So we're seemingly still
better off using tar.exe, at least for creating tars. Which maybe we
don't want to do.

Yes, just look at what happened to tar.exe when it tried to read BSD
tar files! This is an ancient file format seemingly with some weird
quirks.
