Are there any plans on how this feature would look like in more detail?
A daemon monitoring various performance indicators and updating node
attributes accordingly? Couldn't that be done today, as a cloneable
resource agent?

Or are you referring to missing features actually evaluating such
information, as in, rather than saying "run this resource on a node with
at load average of X or less", being able to say "run this resource on
the node with the currently lowest load average"?

Cheers,
Florian
