Does it matter if there is more than one subject tree?
It seems quite reasonable to have one for computer scientists, with
Anders' bias, and anoter with bias of a traditional librarian.
A bias is not a bad thing, it is a starting point.

It might seem confusing when there are few subjects implemented,
but when the SEPA have been subdivided so that they are looking after

History/French/18th Century

then in fact only the top level of the tree will be different,
perhaps all the bottom trees will be in common.
The tree will have two roots. Its only when you have to
uniquely number the things that you force a single subject tree.
