I find it funny(ironic) that the OpenBSD project is trying hard to go the other way, every single install has unique and randomized address offsets.
While I understand that these two goals, reproducible builds and unique installs, are orthogonal to each other, both can be had at the same time, the duality of the situation still makes me laugh.
If the address offsets can be randomized with a provided seed, then demonstrating reproducibility is still possible.
Alternatively, randomizing the offsets when starting the program is another way to keep reproducibility and even increase security; the offsets would change at every run.
OpenBSD does randomised linking at boot time. Packages themselves can still be reproducible. All the randomisation is done locally after the packages are downloaded and their checksums validated.
