I am against to force mandatory review, as it will create a lot of lose of 
time, and we will not be sure that review is correct (see comment from Volker 
about "transaction lock regression")

It's necessary to having a big team for doing it.

Ok a repo was broken, but it was just that fix was created in master not 
19.04, I didn't see nobody on IRC told us "this package is always broken", 
when I saw it this morning I just cherry pick (2 seconds for fixing it).

For example I works all days on kde (pim or other) when I wake up, or at noon 
after my lunch or the evening, I will not wait several days for a review 
because nobody has time to do it. (we can see a review from zanshin for 
example we can see that David waited 2 
months until having an answer...).

(For example I make ~ 15 commits by days on pim/ruqola/framework, I don't want 
to wait several days/weeks until someone wants to review my patchs)

I will not lose my time to review some code that I don't understand... I never 
reviewed Akonadi patch as I don't understand this code, and I will take time 
on it just for the pleasure as I prefer fixing bug or adding new features in 
components that I maintain.

When we have a big team as Qt team it can help but in pim component where we 
don't have any redundant guy, we will lose a lot of time.

So for each increase version for each package I will wait a review. For sure 

Each time that I will improve code as coding style I will wait that someone 
wants to review...

I know that it's easy to write "make reviews mandatory" there is not an impact 
about your work as we know that you are not really active on kde at the 

For sure I broke kcontact 2 days ago, but as a friend told me when I started 
to work on kde "We can't create a bug when we don't code..."
