There is a very clear reason and that is:

After this operation, 37.9 MB of additional disk space will be used.

Yes, thats right, that is the size of the python-scipy package in Debian 
Unstable.

So I am glad to intend to remove the dependency, as I really would like to 
move fiologparser to /usr/bin, but that means currently python-scipy would 
need to become a hard dependency and I am probably not going to do that.

So for fiologparser to move into a more promiment location, I´d need it to be 
free of that dependency.

Thank you,
