I submitted an update with your suggestions #1 and #2 but this #3 is much more difficult because of the nature of `%{t:real}`. I'm not sure I can have a source/target path that includes symlinks in a way that allows me to test this, and even more so with substitute drives since we can't know which drive letters are unallocated.
