The problem with this is that you don't know what future conflicts will be. You spend years training yourself to use your own "jq" alias and then you find yourself needing to use the "jq" program and you have to remember to prefix it with backslash every time you use it (including when you copy-and-paste a command line from a webpage), or rename your own alias and re-train yourself to use its new name.
