Restoring the original modification times of all files, source and generated, in the working tree would certainly not break make projects. On the contrary, it would cause make to figure out correctly which files were newer than which other ones.

While someone is writing this hypothetical future plugin, they should store and restore file permissions and ACLs too. Thanks in advance :)
