Regarding the packages, those are very respectable numbers... But who is maintaining them? It takes a lot of effort to maintain a repo up to date, with patches both functional and security related. This is in most distros a full time job for a group of people. For comparison pkgsrc has 19444 packages, and it takes a substantial effort to keep up to date.
Regarding 4... I am not sure about your angle there... "Running random binaries" is risky. Technically hysp is a random binary itself, from a random source. I don´t know who you are, and even in that case any certification of authority is best efforts. You can´t certify that the code you built has not been compromised... This is a tough problem, good ideas are still needed!
OTOH, maybe you could leverage the work of the pkgsrc team to increase the number of available packages, traceability, and portability! Join forces! Synergy!!!!
