You could use eRuby with any .extension
In fact you could serve web pages with any or no dot extension.
The key is that the server knows what to do with it.
An example is Apache. You tell Apache what to do with files of  
various extensions. You could tell it to parse all .html files with  
Ruby, or all .php files with Perl.
Thus, many rails pages show URL/URI with no dot extension at all in  
the web browser. It is important only if you use multiple language  
interpreters or your web application framework requires it.
