Yes. I should have talked to you more at the conference...
I will do it next time!

Can we discuss how to proceed this improvement?

There are 2 approaches for it:

1. Do the followings concurrently:
a. Implementing small changes that got a consensus and
merge them step-by-step
(e.g. We got a consensus that we need to extract the
current format related routines.)
b. Discuss design

(v1-v3 patches use this approach.)

2. Implement one (large) complete patch set with design
discussion and merge it

(v4- patches use this approach.)

Which approach is preferred? (Or should we choose another
approach?)

I thought that 1. is preferred because it will reduce review
cost. So I chose 1.

If 2. is preferred, I'll use 2. (I'll add more changes to
the latest patch.)

Thanks,
