Global themes not in ASP.NET Beta1

I noticed this last week but it came up again on a recent thread... the global Theme styles which had been in the ASP.NET V2 alpha's have disappeared in Beta 1.

In the alpha's there had been 2 of them: BasicBlue and SmokeAndGlass. These were located in (WINDOWS)\Microsoft.Net\Framework\(VERSION)\ASP.NETClientFiles\Themes.  It was my understanding that the ASP team had intended to add more themes so I'm not sure as to why they are not in the Beta. 

Of course, if you still have the themes from the Alpha's you can simply add them to a Themes dir. in your applications and I presume that you could still manually add them to the global dir. and have them work too.
