If you examine the layer.srs object, you already have all the srs child 
nodes of the layer, and you can also walk through them easily:

For an array, you would do
for(var i=0; i<layer.srs.length; i++) {
    alert(layer.srs[i]);
};

For the object, all you have to do instead is
for(var i in layer.srs) {
    alert(i);
}

If you e.g. want to populate a dropdown form field with the available 
srs values, this does not make any difference.

Not that I am aware of.
