Confusing use of lightest term

The module doc statint that it should act as :

• home >> term >> term
• mysite >> term >> term
• home >> vocabulary >> term >> term
• vocabulary >> term >> term

I have a content associated to 3 terms, this way : Term 1 >> Term 2 >> Term 3 .

As taxonomy_breadcrumb pick the lightest term the bredcrumb will be printed as :
Home >> Term 1 >> My Content

In _taxonomy_breadcrumb_node_get_lightest_term(), if I $vtree = array_reverse($vtree);

I'll get the right breadcrum trail, like :
Home >> Term 1 >> Term 2 >> Term 3 >> My content.

Shouldn't we provide an option to pick the lighest or the heaviest taxonomy term.
