Re "fix or not fix". Re "do I care about someone's broken mouses". Simple example. I have nearby such asphalt path (see pic, red part). This is not a joke, the shape is really stupid. Anyway, people of course go just directly through the lawn (see orange part on pic). And we have here a holywar about "is this a designer's responsibility to lay correct path shapes?". Two answers:
1. No. This is completely responsibility of people. Every man can choose correct path and should follow the rules
2. Designer KNEW that people WILL choose orange path and DESPITE THIS he choose red shape
Re "broken mouse". I have googled, double click is a common problem, many people have such from time to time. OS Windows even have a setting for a double click duration, though I can't say for sure for what reasons it has been created.
If solution "if rmb is hold pressed, engage battle" is a relatively quick to implement, it would be great to implement. If this is not quick for some reasons, then, of course, there are a lot of much more important stuff, like multiplayer. And in case if it is relatively simple to implement, but designer decide that people should keep their mouses healthy, then we have "path designer" situation: designer KNOW that this an issue for people, KNOW that people will anyway play with broken mouses and keyboards will be smashed from time to time, but still designed strange pattern. People are not squares, people are not triangles, people are different, this is why devs implemented different modes, like survival, builder etc, sandbox and even mods system. And of course people have broken mouses with double click, this is much more common issue than you think
