capsdebug is equal to the "onlycaps" property in your element. The data dumping
and events can be done with identity. If needed I would not mind having a
dump-max-size property on identity to limmit the dump to first/last n-bytes.

capsdebug and identity can be kept in the pipeline as well.

I would prefer to add the features to existing elements to avoid the overlap.
Also gst-tracelib can be used to get a lot of info from a running pipleine:
