People make mistakes and it's been agreed that introducing these aliases years ago was a mistake, albeit I think back then an understandable mistakes, given the idea to bring a shell to windows that has the power of a traditional unix shell.
Now people are loudly complaining, laughing, etc but without any constructive feedback that takes the backwards compatibility needs of a tool that is literally shipped to hundreds of million of people into account and stomping RFC approaches that are pretty similar to those in other projects (see PHP RFCs, Python PIPs, etc).
Since when did people became so hostile towards open source projects that try to do the right thing?
