I'm in favour of the removal of barriers, however, there still needs to be sufficient tactile areas near road crossings so that blind people and guide dogs can identify the safest places to cross.

One of Boris' pet projects, shared streets, is being opposed by Guide Dogs for the Blind, Action for Blind People and RNIB. That is where the pedestrianised areas are created that still allow traffic through, with the effect that VI people can't tell where the pavement ends and the road begins. That's a step too far.
