What's the point of trading 7z's compression for a plain TAR?

The destination is a toolchain, not a shelf. Make, Docker, and CI systems ingest tarballs directly, and minimal server images rarely include p7zip — while tar is guaranteed present on every Unix system. Compression gets reapplied downstream as .tar.gz or .tar.zst anyway.

How large will the resulting tarball be?

Roughly the raw size of the extracted contents plus a header per file — TAR itself performs zero compression. If the 7z held highly compressible data like source code or logs, a tenfold size increase is normal until the tarball is gzipped.

What can a TAR do that the 7z couldn't?

Stream. Tarballs pipe through standard input and output — tar -x over ssh, docker load, streaming backups — with no random access required, something 7z's container format doesn't support. That is why deployment pipelines standardise on tar even though 7z compresses far better.
