Lars,
Thats great news.
I also understand the issue about existing packages.
One of the problem though is that when something like this happens, the community is ware at them time, but a month or two later it'll be forgotten.
Is it worth you (or anyone) putting together at the very least a brief checklist/plan of everything that needs to be converted? Something we can keep publicly visible to both inform and maybe encourage others to make these changes?
