I don't have the statistics on releases published each day, but I suppose it's 
more than 500 (yes, each day)

It's clear that currently, Reproducible Builds for projects publishing to 
Maven Central is a minority

But it's not a surprise: we're talking about upstream projects, that do their 
normal releases. And tooling to have good chances of getting Reproducible 
Builds easily for "normal" people just wanting to get a result without having 
too much work is quite recent.

Then I see this result more as a proof that upstream projects can have 
Reproducible Builds (and not only rebuilds done in the centrally managed 
environment of a Linux distro): it works without adding much constraints.

It's really an important proof of feasibility at scale, before more projects 
embrace the movement.
