Precisely, they are 3 cases in the FAQ. The first the exec/fork which
is not applied here. The second which looks very close to most of our
cases. This one is clearly not a strong statement ("we believe") and
also it is stated that you can use any GPL-compatible license which
include BSD/MIT (that you seems preferred).
Finally the third one, which is more the case of a complete independent
module using only the Tryton framework (Tryton will only call the 'main'
functions CRUD).

Of course, but it only applies on specialized classes. General purpose
classes are not included in the case. That why we keep stating that it
depends on the case (derivative work or not).

It is already the case. Some people already publish modules under the
BSD license.
