For me it seems like a good idea, as I found the current Logger very
useful :) Anyone?

I'm not sure if duplicating the LoadSensor approach is good here. You
would then log everything send by a given node (by any of it's output
events), which may be too much information. Advantage of current
Logger: it allows to log only a chosen (single) output event. The
disadvantage of current logger: requires adding a very special XFAny
field type. Implementing XFAny is absolutely trivial in my experience,
but I understand that it may be an unwanted complication to the spec,
especially if needed only by a Logger node.

Can other implementors and users comment of the usefulness / ease of
implementation of current Logger? Specs:
