Possible workaround would be to keep original file path as a comment inside new file. In this case history of ex-WebKit tests can be easily retraced from WebKit repository. > > Regression tests are taking an excessive amount of time to run for us (more > than 1.5 hours in a debug build), a very large proportion of which is WPT.
