IMO this is a gimmick and probably won't have much effect either for good or bad. I would vote against it given the chance. But there aren't that many British people who feel especially strongly about this.
In the last 10 years the UK has had 4 general elections and the Brexit referendum. Some countries have more local democracy (e.g. direct elections of DAs in the US), but in terms of opportunities to change the national government or influence national policy, I don't think the UK is doing too badly.
