Disk space is cheap. Database schema changes are not. Updates require testing as well as validation in all of the UI and UX environments.
Indexes of int are easy and great. Indexes of Char, VarChar, or NVarChar are necessary. How the rdbms does such, and how the dba defines the index to accept insert as well as an update is where the true performance lies.
