Yes, but:

  - It depends on what you do.  In my example (thousands of small files), you
  get a significant gain in permanent space for a minimal cost in temporary
  space.

  - It's only an implementation issue.  It can be fixed later by implementing
  streaming properly.

  - It doesn't need to be better in *everything*.  p7zip is also much slower
  than gzip or even bzip2.  Giving users the choice can't make it worse (if/when
  they don't want it, they won't use it).
