Something the Rust project does is prefix all their labels with a single letter to have alphabetical sorting keep similar labels together. For instance, using the "T - " prefix to group all type-related label like bugfix, enhancement, etc. This is all done to make it easy to find all labels for a certain thing.

Do people like this idea for labels that don't naturally have a common prefix? If so would people want the single letter prefix or full word prefixes?
