Large professional software has components like COM servers, or several executables sharing the same app code which then goes in a DLL. What they don't do is divide up their DLLs any more than necessary. An open source library could be a DLL to comply with LGPL but it won't be one just because they can, while on Linux it would be a separate .so because it's separately updated. What are you making?
