Possible hacks that need to be or can be changed now are:
1. In the old implementation there was the requirement to have a rule in 
the polygons file for polygons for which a POI should be added. Some 
people added rules with transparent polygons so that the POI is visible 
but the polygon is not. This is no longer necessary. A rule in the 
points file is enough if you want to display the POI but not the polygon.

2. For the same reason you might have to change you points style now 
because for polygons that are not defined in the polygons style a POI is 
added anyhow if there is a rule in the points style. So you might add a 
rule like:
aeroway=terminal & mkgmap:area2poi!=true [0x2f04 resolution 22]
