+==Unscheduled / post-hoc / one-off relicensing==
+
+This is probably properly outside the scope of this research, but people
+often suggest things like these as examples when asked for projects whose
+open source publication was "delayed".
+
+* Netscape Navigator
+* Blender
+* StarOffice
+* Qt
+
+... and probably dozens, if not hundreds, of codebases that were released
+after companies that were developing them shut down.
+
+Maybe more ambiguous cases:
+
+* Games from id software (routinely released/relicensed after the end of
+  their main commercial viability, but not on a schedule and not with a
+  public commitment to do so?)
