1. Not all packages but only those whose maintainers explicitly opt in.

Yes, at the first stage. But over time the number of packages can increase significantly.

2. The duplication will affect only the executable ELFs - i.e. the contents of `/usr/bin` - shipped by these packages. There will be no duplication of shared libraries, data files or anything else.

Shared libraries used by affected packages should also be rebuilt with these optimizations. For example, Firefox has most of its logic in *.so files.

One effect this *will* have is a slightly increased latency for launching an affected program.

How much?
