The SQL files also need updating too.

https://github.com/joomla/joomla-cms/blob/staging/installation/sql/mysql/joomla.sql#L506

"source_formats":"txt,less,ini,xml,js,php,css"

replace with:

"source_formats":"txt,less,ini,xml,js,php,css,sass,scss"

Unless this is done, people will manually need to go to the Template Options and manually add them.

Add a .scss or .sass to the Isis template directory and you'll notice it doesn't display the file when viewing the folder/files in the Template Manager.

Correct for 3.x we need to do this as we cant and should not override the entry in the database that maybe has ben changed to something different.
