Sure (if you accept that the street sign put up by the council is more
authoritative than the Ordnance Survey's database, which actually I doubt).

However, given only an hour or two to survey Exeter this weekend I would prefer
to concentrate on more important things than missing apostrophes.  Others have
different priorities, of course.

For my own use I would prefer to see a report that flagged only the real
differences in name, ignoring punctuation.  I expect some other mappers would
feel the same - while others might still prefer to flag every difference in name,
no matter how small.

The ITO report is also useful for armchair mapping, adding names to roads that
lack them or fixing obvious and definite typos or spelling errors (but only when
you can be 100% sure the OSM data is a spelling mistake).  Here too the
punctuation-only differences tend to crowd out the more important and more
easily fixable mismatches.
