I am supporting the idea of having additional categorized POI icons too. At the end it is just a personal preference which one you use. At Google MyMaps there are more icons to choose from and if you see how they solved the issue with too many to display, you have a very splendid example how to manage many icons.
a) you have the standard icons (Beliebte Symbole) always available

in addition, "Andere Symbole" is showing "recently used" icons - the translation Google used here is not correct in the sense what the functionality is about
b) clicking on "Weitere Symbole" (more icons) you get the categorized overview with a search option top right

Benefits, you have your recent icons available on a fingertip, tons of choices well categorized and searchable, you can define your own colour (having a larger colour choice too I believe).
This said, importing POI's from MyMaps or any other sources like POIBase to MRA and taking the symbol and colour into account would be perfect. But who is perfect at the end?
