I don't know anything about #blender geometry nodes...
I literally CAN'T use geometry nodes because i'm limited to the version of blender i can run.

So i was wondering how far could i go if i learn to code enough to use the python API as a substitute....

Not that i have needed to use geometry nodes ever... personally i think that geonodes are more useful for people in the field of motion graphics and pros doing a bunch of procedural stuff more than a humble generalist like myself.
