Three PRs out on GitHub for Subversion spanning years - https://github.com/apache/subversion/pulls
^ "join in" versus "don't join" in is communicated via team welcoming, curating, and consuming of PRs in this age. Sure, Julian's shelve tech is the starting point of a PR system for Subversion itself, but that doesn't mean Svn development can't take advantage of a workflow that millions of devs have adopted today on GitHub. To say no to that *feels like* an arbitrary policy. Towards that in GitHub-land, people dread bug reports remaining unattended. Issues in GH is turned off, of course. They also are put off by incomplete READMEs. Ref https://www.makeareadme.com/ (I have made contribs to that) and a few similar efforts. Lots to say on Svn's README.
