This is pining for a world which no longer exists, because security patches must be applied to anything that matters immediately.
Of course you do need a strategy for maintaining multiple versions of something in that case instead of just forcing the latest version of everything you do on users whether they want it or not. With the lock-in effects of the always-connected web applications of today we all know which option makes more money.
I take some comfort in knowing that eventually most of the developers that force unwanted changes on their users will probably see their market share erode and lose their dominant positions. It's just unfortunate that we have so many quasi-monopolies in both essential and niche software products that it's going to take a long time for that to happen.
This world does in fact still exist, this is how most OSS works!
Given the tone of the message, I expect "non rapid" to mean with a much longer time frame, and, most importantly, the release must be controllable by the user.
