Sorry, but I just have to ask 'why'? IDE is seeing a whole lot of churn
for something that should essentially be a stable code base in
maintenance mode, and now scalability improvements?

Just doesn't make ANY sense to me, sorry. We may end up with a cleaner
code base, but likely also a buggier one. It's not like hardware
coverage testing is all that great, considering some of the ancient
stuff it supports :-)
