Hi again!

1) what do you want photographic evidence of? the sign at the top of Silvocea Way ( https://ibb.co/WK6SR0z ) or the toucan crossing at the southern end ( https://ibb.co/MC5Ww6v )? a lack of dismount signs on the vast majority of these paths (your own survey showed that)?

2) we agree that there is a lack of signage on most of these paths

3) that behaviour is implied by the highway=footway tag which is already in place, and a bicycle=dismount tag shouldn't be added unless it's explicitly signed on the ground (and the only sign I'm aware of is at the southern end to the pathway through London City Island, but literally none of the other entrances to that area, at least none that I saw yesterday)
