Due to Spectra/meltdown etc, indirection is now expensive. But i guess
the I2C operations are a lot more expensive.

But in general, we try to keep the code KISS. Have you tried other
ways of doing this. Have your unit test framework implement

There are different 'timers'. One is how long to wait for review
comments, and reposting when you don't receiver any comments. netdev
for example is fast, a couple of days. Other subsystems, you need to
wait two weeks. Another 'timer' is how often to post new versions. In
general, never more than once per day. And the slower the subsystem is
for making reviews, the longer you should wait for additional review

What also plays a role is that the merge window is currently open. So
most subsystems won't accept patches at the moment. You need to wait
until it closes before submitting patches you expect to be good enough
to be accepted.
