the dst code i am rewriting is quite heavily changing at the moment, and 
there are quite some changes to what exactly is in the current dst 
module.. The entry point for the dst, dst_ca module is in the dvb-bt8xx 
module, even for the new modules that i am working on..

Removing that/and or reorganising that part would be quite difficult, 
and possibly lead to abandon the development what i have already done in 
that area..

It is really true that so much effort has gone into getting the dst 
module to work at least to quite some extent.. And such a large change 
would possibly would lead to an extreme large workload at this point 
time, which cannot be done considering so much additional work has to go 
into the various dst based cards, since being a combo driver.

Without all that work, the dst module will look like a standard FTA 
based card only.. I mean it would be extremely hard to get the features 
of the hardware into driver..

I know you meant well by proposing this change but I'm afraid that the 
impact are too large to ignore. Feel free to
come back later, if you have other idea to make bt8xx structure more clear.
