It seems the feature is badly understood. I'll try to explain further. There
are elements with lots of settings (gobject properties). Its useful to be able
to have  named parameter settings (multiple parameters, one name). Can we agree
on this?

Now applications need a defined interface to scan available presets, activate
one of those, or store the current as a new preset. It would definitely be
possible to handle this inside the app too. The downsides would be that the
code would be duplicated in various applications and elements can not override
the implementation. All the wrapper-plugins (ladspa, buzz, libvisual, ...)
would want to support the native preset format (if there is one).

The idea of the current implementation is to provide something that can be used
by  most elements as it is. The more special case an element is the more likely
it will need to override things.

The implementation was available for almost a year and I annouced it on the
mailing list and irc. Noone objected. There are some todos which need
discussion, but a new core lifecycle just started, so lets discuss and I will
make the changes. I've sent another mail to gst-devel regarding that.
