Hi,

I would prefer B (the first B ;-) ).
To have an own paramter-object gives the programmer more freedom to
define all necessary validation and it represents the oo-way of
encapsulation.
The other thing is, that in the beta-branch it is planned to have a
global registry-object also for the parameters, so access will be
extremly simple from all parts of the extension.
