I agree that we want to try and have a complete main road network network.
Whilst longish stretches of road are easy to spot there are a lot of
other small sections (eg. bridges) which are harder to see on cleanmap
(unless the rest of the area is clean).
We also have the issue of nodes going at highway junctions. Even if the
ways stay we may loose the critical join. There a still a number of
motorway junctions like this across the UK (and there must be plenty on
trunk roads). You need OSMI to see these and with things like footpaths
(which we can't remap remotely) adding to the red it is very difficult
to spot. I do wonder if it would be easier to erase things we can't
remap so we can identify more easily those we can.
As Robert says getting a list of problem highway nodes/ways would be a
good step.

We're almost certainly not going to be able to able to get the UK
completely clean by the switch-over, and it's definitely good if we
can prioritise work on particularly badly-tainted areas. But I wonder
if another prioritisation approach might be useful too -- prioritising
certain high-value types of objects, where-ever they might be.
For instance, as far as routing is concerned, any gaps in the major
road network is likely to cause significant problems for data-users.
So might it be possible for someone to generate a list of
highway=motorway and highway=trunk objects that are tainted, so people
could work on eliminating those. The idea could extended to include
the corresponding *_link ways, and if progress is good we could
continue to do highway=primary and highway=secondary.
We might want to do the same for railway=rail and perhaps
waterway=river. Are there any other types of object people can think
of that might be worth prioritising?
You can sort of look for these types of object using BadMap [1] at low
zooms, but it's not that easy, and the low zooms aren't updated as
often I don't think. It would be much easier if there was a specific
list of objects to work from. I'm afraid I don't have the hardware /
experience / technical expertise to generate the data sets, but maybe
someone who does might think it's a good idea...
