The harder it gets to release add-ons, the fewer add-ons you'll get for free.
I've already abandoned all but one of my add-ons, and barely have the will to keep that one up to date.
If I had to get a cert from somebody, or update my add-on every time there's an API bump even if no code needed to change? I'd just stop publishing add-ons entirely. I have better ways to spend my gaming time than programming for free.
PS: And yes, I look forward to switching WritWorthy to the new library scheme just like Baertram. I suffered through a rash of library version incompatibilities about a year ago that wouldn't have happened if I had the new system back then.
