Looks very similar to JEDI [0], an early Delphi VCS system that worked that way. It gave us the tranquility to know that no conflict would appear, as only one developer could work with a locked/checked out file at a time. There was no merge those days. In contrast, files that were frequently changed in every task would always cause a blocking between developers. [0] https://jedivcs.sourceforge.net/ https://jedivcs.sourceforge.net/
