except that debian's apt repo style have been there for decades and still worked well, redhat/fedora's pkg and development model instead had changed who knows how many times, and of course the current one is the golden one, until next one arrives that is.

The current RPM repository metadata format has existed since Fedora Core 2 in 2004. The build system infrastructure changed to Koji in 2007[1]. The development model has changed exactly once when Fedora switched from CVS to Git in 2009[2].

There have been no significant changes to Fedora packaging model until three years ago, when Modularity was introduced[3] and Pagure was deployed to ease contributions and support building modules[4]. And the modularity concept is primarily used for alternate software streams in Fedora, so the vast majority of Fedora packages don't use this feature.
