Refactor ICU tools to use PathMatcher API from CLDR code (and delete ICU version)
was for adding a better PathMatcher API into the CLDR API.
This is done, but now the existing ICU code needs to be migrated to use it. This will entail some refactoring since the CLDR version of PathMatcher is a better API, with less chance for accidental misuse.
Once this is done the pseudo locale functionality can be moved from ICU to the CLDR API (it becomes just another locale you can get data for).
Good idea, please do this
