iGoogle features no longer supported in Orkut sandbox?

[Jerome]

I noticed today that my 0.5 gadget is giving 404 errors. I removed the
following Require feature directives, and then it loads fine (but
obviously stop working fine):

<Require feature="analytics" />
<Require feature="minimessage"/>
<Require feature="setprefs"/>

Is the support for most iGoogle features gone by mistake, or is this
how things are going to work moving forward?

I can surely do without Analytics and Mini Message. The iGoogle Prefs
management has surely be useful. The little tool icon on the bottom
left of the gadget on Orkut has vanished as well, so it sounds like
this is not only the setprefs feature, but the user prefs management
that is gone.

Please, comment whether or not this is a permanent chance, or just a
bug from the recent 0.6 update.

Thanks,

Jerome
