[GraphHopper] Why is kissing_gate apparently an blocking barrier for mtb routing?

Hi,

we have indeed marked some barriers as 'absolute' barriers where even a

I just saw that this was changed, great. However, I'm not quite sure if I
interpret the code correctly, but doesn't BikeFlagEncoder still block a
kissing_gate even if there's a bicycle=true flag?

BikeFlagEncoderTest.java:

// kissing_gate with bicycle tag
node = new OSMNode(1, -1, -1);
node.setTag("barrier", "kissing_gate");
node.setTag("bicycle", "yes");
// barrier!
assertFalse(encoder.handleNodeTags(node) == 0);

If my interpretation is correct, I think that implementation is wrong. In
our parts of the world, we have plenty of kissing_gates and turnstiles,
which primarily block cows and maybe cars but not bikes, regardless of
type. Hence the bicycle=yes tag...

cheers,
Armin
