As you say, supporting these old versions is effectively zero-cost, so how does this project benefit from these changes which potentially "break" Git for users on older platforms? I see no upside here. The cover letter provides no strong justification for (potentially) inconveniencing people; the argument about being able to utilize more modern Perl features is weak[1] at best and is not convincing. Although brian is (quite rightly) concerned about security (or lack thereof with older installations), it is not this project's responsibility to "force" people to upgrade their insecure installations. And it is not at all uncommon in the "Real World" for decade-or-more old installations to be running in production environments, and programmers need to work within those environments, however, those installations are, for various business reasons (such as cost-effectiveness and known stability), unlikely to (ever) be upgraded to more modern versions. I, personally, deal with such installations on a very regular basis, and in my experience, the only time upgrades are undertaken (in production settings) is when the systems break completely and there is no choice but to replace them. Finally, there clearly are real-world cases[2] which benefit from Git continuing to support older platforms; why should we abandon them intentionally? And why should we turn down[3] the periodic trivial patch[4] which trickles in to help people on older platforms?
