Thanks for Boris's clarification.

It's hard to find the balance between short term(sharing codes) and long
term(splitting codes).
Current I think we'd better try to follow the following way:
For current version, we will try to minimize the modification and share
codes,
For later big modification, will try to split codes to make code path
more clear.
