[Talk-GB] traffic island mapping / harmful detail?

When people decide to map a small pedestrian island with separate highways
are there any suggestions for good practice? I was wondering if it would be
helpful to just skirt the island with the highways and use
placement=right_of:1 for example to minimise the effect on standard maps?
If the overall carriageway is straight is there a maximum angle from the
single way we should look to use to avoid triggering turn instructions in
routers, or is it preferable to run the single carriageway up to the edge
of the island, etc (this applies for big splits too).
Are there benefits for pedestrians from this approach in the absence of
separate sidewalks (the router I use wouldn't know how to use them - it
doesn't imagine the sidewalk).
Also, I wasn't sure from the changeset comments if the island had been
mapped as an area and if the tagging for that was disputed?
