Example of where the ability to add a string to key would help:
annex.genmetadata stores year, month, and day metadata, from the file's modification date; but this will be silently overwritten if later other files with the same key but different modtime are added. On the other hand, if I specified in .gitattributes that a random string uXXXXXX be included in the key, git-annex metadata would in effect become per-file, so one could attach metadata without worrying that it could get silently overwritten.
An heuristic alternative is to add an option to metadata --get to use the field value from the time the file was committed, rather than the current value. But this doesn't cover the case
of two same-content files in the same commit.
