> renaming will be much cheaper if you're renaming to descriptive names

Idk, renaming things that shipped is a PITA.

Say you wanted to rename `fish` to `a-decent-shell`. - Packages in all distros would need to be renamed. - Configuration for all systems using/having fish would need to change. - Scripts would need to change, from the shebang to the contents if necessary. - Users would need to understand that they now need to search documentation using the new name. - Documentation would need to be migrated to new domains, sed-replaced, and reviewed.

All this migration would require some synchronized, multi-step process across multiple distros and deployments.

I'd rather have a name that works as an Id.
