Review comment:
I can totally understand your point about minimizing the changes, but I
personally don't think it's a big issue given that we only have a few existing
codegen. Since BYOC is getting mature, we should avoid ad hoc implementation as
we can. In fact, we are planning to do another refactoring to cleanup redundant
code.
The changing (or addition) of annotate target, which is one of the most
important interfaces to codegen developers, are better to start with an RFC. It
is fine even the RFC is small and simple. The main purposes are 1) making sure
this change is compatible to all cases, and 2) letting everyone know you are
going to make this change.
