Small or big dub packages

[Igor]

Can someone tell me what are pros and cons of having multiple 
extra small dub packages that depend on each other versus one dub 
package that has a bunch of functionality? Good example for this 
is dlib (https://github.com/gecko0307/dlib). It has many 
functionalities that could be split into separate packages.

The way I see it the advantage of smaller packages is that users 
can pick and choose and and only have the code they really need 
in their project, but the con could become managing a lot of 
dependencies. Also I am not sure how compile time on clean 
project and previously compiled project would be affected.
