No need for tht.
You can use an AreoOnArea overlayer to test for relative overlaps.
It is not complicated to do so.
,
I don't think an upgrade is nescessary for that.
You need to use a AreOnArea overlayer.
First create a area attribute for inputstreams by ID and fme_feature_type (or create a feature_type attribute yourself). (if objects to be compared are from a transformer, you can name the transformer and then expose fme_feature_type)
Create a area attribute (for instance "original_area")
Then use AoA with a list attribute set.
After AoA you do a areacalculator named like "overlap_area".
Create a string using a stringconcatenator on the list ID.
Test on overlaps >1.
Then use a tester to test if some or more ID's are within this string (with the "IN" test).
Then calculate percentage of contributing ID's (
round(100*"overlap_area"/"original_area"))
Then test if it's 80% (or whatever precentage is required).
If it's just two different ID's things are easy.
If more then testing is more extensiv.
You can, after selection, aquire original area'by using a merger on the ID attribute. ( or rdissolve them on ID and feature_type)

@gio Can you please elaborate on the "IN" test?

I still see a many-to-one number of steps involved rather than an optional percent-overlap parameter.
However, I'm very appreciative for you showing how to get it done!
@vasuki A IN (a,b,h)
search in concatenated list
The overlay is core, even if you put process in a tcl or python caller.
