They prevent bugs caused by inconsistent naming between different plugins and different variants of the same plugins, when a user may not know by heart which plugins use user and which use username.
This mostly works, but the alias set in meltano.yml is currently also considered a "custom setting", and is incorrectly passed to the plugin by that name and listed as such in meltano config <plugin>.
