You've misunderstood. The "dstat" package was removed from Fedora, rather than have its contents replaced. The package containing the new program is called "pcp-dstat", so they already did everything you think they should have done.
lists a file called '/usr/bin/dstat'. The pcp-system-tools package obsoletes a package called 'dstat'. If you go to https://pkgs.org/download/dstat, and look under "Fedora 30," you get pcp-system-tools.
[Spoiler: 'yum install dstat' installs pcp-system-tools, which has a symlink /usr/bin/dstat -> /usr/libexec/pcp/bin/pcp-dstat.]
An alias to the replacement is not the same as silently replacing the package. Yes, the user who care will notice - it's a tool for sysadmins, and the ones worth their salt are already familiar with precisely this provision in package managers, and it's included for precisely this reason. There's always politics involved in replacing a tool, but they didn't steal his namespace - they made the decision to package their own alternative, and yes, that editorial decision does lie with the distribution.
To quote a comment from a dstat collaborator from the above linked thread-
> That said I don't fault you for make a new tool that does all the new fancy things you mentioned above, I do think it's a little sketchy to make a new tool called dstat without at least asking here first. I know that when I hit Fedora 29 and did a yum install dstat and I get a bunch of pcp stuff I was pretty confused.
The way they have things aliased right now, if you type in `yum install dstat` you will get this new program (including all of its baggage).
