You are right, that's not supported, but in general TextSymbolizer is only
used to extract the label to be bound to the imagemap areas.
Would you mean using labels collision to drive areas rendering, or
something different? Can you try to explain your use case?

I am the original author, so definitely I can help you. Currently the
module has no roadmap because there is no funding to work on it, so I think
you have two options:
- I can help you to understand how to do this change by yourself (it
should not be particularly difficult)
- You can ask to one of the companies giving commercial support to
GeoServer to do that for you
For the circle/rectangle rendering of points, you should look at the
PointWriter class inside the HTMLImageMapWriter (here:
https://github.com/geoserver/geoserver/blob/79c756c2ccf4a2c2ec051cefba393854df95a3c5/src/extension/imagemap/src/main/java/org/vfny/geoserver/wms/responses/map/htmlimagemap/HTMLImageMapWriter.java).
I think you need to change the getShape method to return a different shape
based on the current mark and also the writeGeometry method.
If you need commercial support you can look here:

Mauro
