OK, so following this guide, it seems legit. It should be added to the official wiki though, otherwise people will keep merging the segments.

Adding street names to sidewalks is quite essential nowadays, because routing engines use them instead of the street themselves, and without any names on sidewalks, you would get very obscure routing because the complete set of directions would never give you any street name, which would be bad. In Quebec province, I have never seen anyone having problems with this, so I guess it is ok for us.

Thanks!
