Actually, knowing the impact on a list of plugins of an API break would
be a very useful information : an information on where to put the focus
regarding code reviews and what part of code has to be changed for
I don't know if a Python script able to introspect most of the API usage
of a plugin is easily doable ... just an idea

And especially automatic UI testing. I am not sure if we could one day
have some automatic tools to help testing UI, in the meantime human
tests are needed.
Some ideas to improve quality :
- information on who is doing what to the current code is not always
clear among developers (well at least for me ...). Trying to follow
github notifications, mailing lists, QEP, irc and git logs is too time
consuming. So, in order to avoid possible big changes from being merged
without the other devs being informed, could we choose only one channel
for changes that may affect others ? Something like a "purely
informative" PR on github ? With an implicit rule like "If nobody reacts
within a week, it will be merged"
- (re)state when QEP are needed
- try to include documentation when developing a new feature. If unit
tests are not present, this is a minimum to know what the feature is
supposed to do. Some features are not covered by unit tests neither by
documentation, so it is sometimes very hard (and time consuming) to
ensure non-regression ...
