No I don't think anything has changed. I didn't see the rumble strips as indicating no cycling, so much as a warning to slow down. Coming south on the A589 it is clearly a SUP and there is nothing to indicate that stops just there. I came over the crossing over the dual carriageway which is a toucan and there is nothing to tell me not to turn right apart from the rumble strips.

At the other end is a lowered pavement allowing you to cycle onto the road and join the traffic again. I din't see anything to indicate this was a "pedestrian only crossing".  It worked well for me any way.

Anyway it sounds as if you are a lot more local than me, so feel free to change it back if you wish.
