Rendering for ringforts

[b-unicycling]

I would appreciate if ringforts could be rendered different than generic archaeological sites. There are now over 12,000 ringforts mapped, and the number is still rising. I've created an icon of how they could be rendered as a POI, however, I would prefer if they were rendered as an area with a hashed line.
The icon reflects the often (but not always!) circular nature of this archaeological site type, and I've tried to reflect that they can have multiple ditches.

If anyone wants to improve the design, be my guest.

12k uses, almost all of them in Ireland, the vast majority on polygons.

At this stage this is very region specific in its use and we'd get significantly ahead of us if we'd specifically render it. More important at this stage would be rendering of historic=ruins (153k uses #331), possibly as part of a general concept of rendering ruined structures (#331 (comment)) and differentiated rendering of historic=archaeological_site (184k) based on archaeological_site=* (134k) and/or historic:civilization=* (89k). Fill/perimeter rendering of historic=archaeological_site polygons (52k) could also be considered (but would need to be done in a way that works decently in combination with micromapping details on larger sites).
