It is up to the admin to be careful about it. As an admin I may want to be = able to install both to transition from one to another. I can also have both on the same machine, but started with different users = (I already did that in the past with gitea and gogs and they both run fine together. My 2cts is admins should know what they are doing here and there is no reas= on to register a conflict here. It is on purpose that pkg only check for conflict= ing files, until now no cases justified yet any other case of conflict to be ha= ndled by pkg. (If that ever happen then we will implement a conflict handling solution).
