Yeah, you get an hit in that the SLD has to be retrieved and parsed.
Depending on how complex the SLD is, that may be negligible or visible.
And yes, the SLD standard afaik does not allow for a generic style to
be passed around, you always have to assign it to a layer.
&sld is useful is you have the need to dynamically generate styles, like
in the case where an external app does some attribute analisys and 
builds a style on the fly.
