vim plugins are really easy to dash off and can emerge naturally from scratching one's own itches. So they tend to be developed by individuals more often than teams and there is unfortunately some tendency to make a new project rather than co-opting existing ones, particularly when it is performance sensitive as in this case - it may be simpler to just write one designed for performance than to try to retrofit better performance onto a design which isn't well cut out for it.
