Dear mapserver-dev Team,
in context of using mapserver to generate a digital nautical mapchart 
out of s57 data (imported into postgres/postgis), we found two missing  
features to solve this task. Both features can be useful in a lot of 
other areas.
- new feature type ARC, defined by:
STARTANGLE in Degree (west=0/360, north = 90 ,east=180,south=270)
ENDANGLE in degrees or ARCANGLE (negative value means clockwise 
direction) in degrees
RADIUS (meter, miles or whatever)
The feature can be used in the same manner as every other line or 
polygon feature. GD supports drawing of arcs so it should be not a big 
problem to introduce the parameters in the mapfileparser and to handle 
this featuretype inside of the current drawing routines.
- draw a symbol at the center of polygons or lines (it is possible for 
labels so why not using the label offset point for symbol placement in 
the same way); it is possible to solve this inside of PostGIS, but i 
think it would also be a nice function for other datasources.

Thanks for your interest and any feedback to this!
Kind regards

Mit freundlichem Gruß
