The whole pro git discussion is pointless. An inquiry was done in early 2018, and nearly directly release branch management was the problem point.
Over christmas the discussion started again, and it seems the majority of FPC seem to wanti git actually, but somehow solutions are slow coming (or are weak like "separate software has to be written for that"). Nearly anything that is a oneline in SVN is suddenly a separate script(*) in git, and requires workarounds like stuffing metadata in commit messages. THOSE hack SOLUTIONS IS WHY WE FLED FROM CVS, IT IS GOING BACKWARDS !
Note that the GIT vs SVN factions are nearly 100% split over compiler vs other devs, with the exception of Michael whose employer uses GIT already.
If you want to promote git, come up with workflow solutions for release and stable branch management somewhat equal, because that what the migration is hinging on for 1.5 years now.
p.s. Personally I favor staying with SVN, simply because it works, and because I think the migration and solving the problems git outweigh the fairly minor benefits. And yes, if I started a new project I would probably chose GIT. But for many things we already have its advantages via the SVN+GIT bridge, and I don't want the project taking a sabbatical year to recover from a VCS migration
The fact that popularity arguments have to be made to cover up that GIT is so deficient in the current situation, and that it can't simply win on merits (even after people studying 2 years on the issue of those release branches) is IMHO telling. It is simply not versatile enough, too much a "my way or the highway" philosophy.
And the popularity arguments, like the language feature ones, never deliver on their promises. The big unwashed masses never come because of such changes, it is all hot air.
Like many of the propose language features: solutions in search of a problem
(*) and scripts are problems, since FPC is not an *nix only project, and everything has to work on multiple systems. And no, requiring a mingw install for *nix scripting emulation is not acceptable.
