Andy ... something else !
It does appear in the National Street Gazetteer as mixed responsibility for maintenance, which is a good indication of public access.
Feel free to reinstate the fixme if that's not sufficient to warrant the change. 
I try my best to reduce RoW errors & fixme's but clearly if all are going to warrant scrutiny, I'll just leave as is.   
I have been involved in RoW since 1977 with many letters & Public enquiry involvement in my days with he TRF ... so I don't make changes lightly. 
However you will appreciate its not easy especially when working within the bounds of what data is permissible to use, and the occasional incorrect or out of date info I work with.
