I (and 10000kms of riding in all terrain) disagree with you!Not to intentionally initiate a bloody exchange, but... ideally, weighted components should be conveniently mounted elevated, but slightly below the top tube, and forward of the seat on LWB 'bents... not lower.
Mounted lower...
1.) Subjects the component to moisture spray from the front wheel
2.) Ground clearance is reduced.
3.) Negatively impacts handling
4.) Potentially interferes with chain routing
