[Talk-GB] boundary & admin_level tags on ways.

[Colin Smale]

For what it's worth I would like to leave these tags (at least boundary=*) on the ways.

I know it's a rather selfish reason, but when working in Potlatch (as I and many others still do) it shows the boundary way in a distinctive style, so it stands out a bit and is easier to follow. Without a boundary=* tag the ways are rendered as a fine black line, as do millions of other types of way, and it is easy to lose your way when trying to follow a boundary through a web of hedges, field boundaries and all the other fine black lines. Potlatch actually renders boundary=administrative in a different way to boundary={anything else}.

In any case, I would argue that these tags could be considered redundant or superfluous, but not erroneous (assuming they are not erroneous of course). In other words, their presence is not worth the effort to go round deleting them without any other reason to update that way. A bit like the widespread use of oneway=no or access=yes - possibly pointless, but not actually WRONG.

I don't see how could they lead to confusion and erroneous edits though.
