They never worked well for outside code. That's just a fact. Most
stuff will even simply break, dd-list for example. I recently
announced a mass bug filing to fix this.
For those that work but are slow, it's mostly always a issue of
random access to Packages files instead of linear access.
Acquire::gzipIndexes exists since more than 5 years, since
0.7.26~exp10 from 12 Jul 2010 to be precise. Let's make sure
we get it working now that it's actually fast.
