The Subversion project history starts at revision 836420 in the ASF repository. If I want to clone it, one use case for this feature would be to initialize my new repository with 836420 empty revisions. An external loop is going to be slow on this scale. On my machine with SSD disk, "svnmucc mkdir file://..." takes 1/8 sec and even "svnadmin delrevprop" takes 1/25 sec, so that's looking like taking a substantial proportion of a *day* to complete 836420 commits. That's one reason why I think the UI should allow specifying how many revisions to create. Even if an initial implementation with an internal loop is currently no faster, at least it opens the possibility of changing the implementation later. - Julian
