By the way, upstream libstore itself supports gzip & bzip2; I have
only briefly looked into why tarfs needs to ship its own
implementation. Upstream libstore seems to only support store_gunzip
and store_bunzip2, which, to quote the docs, "contains a snapshot of
the uncompressed contents of the store FROM". The version shipped with
tarfs has store_gzip and store_bzip2, seemingly providing both reading
and writing support.

Any idea why the implementations have not been upstreamed?
