You should never change any of the files that ship with SharePoint, including any XML files, ASPX files, or CSS files in the 12-hive.
If you change any of these files, Microsoft may refuse to support your SharePoint installation.
The only thing you can change is to alter the Hidden attribute of Template elements in the default webtemp.xml file to hide or show the built-in site definitions.

best practices are sometime away from reality and just good for books
This best practice is actually very good.
Consider that Microsoft, in any update, may choose to ovewrite any of the files they have provided, and it makes more sense. Any change you have made will be lost in this case.
It’s not just a good idea, it is the paw…
