It seems to me that if a plugin developer cannot be bothered to make their plugin A) compatible with the latest version and B) work smoothly with the core update functions now in WordPress that WordPress should remove the plugin from the site's extend/plugins list. Conversely, it should REWARD those developers who DO put in the time and effort to keep their plugin tuned up. IMO, the plugins list should ONLY contain plugins that are compatible with the latest version, OR, at the very least, should allow filtering by WordPress version.
And before anyone reminds me that plugins are free... contrary to the popular whine, plugin authors DO benefit from their "free" plugins -- they gain community expertise and stature that helps them in their profession, for the most part. For example, there are key SEO plugins developers who project themselves as experts and get work based on that, charging a fat rate for their services.
Sure, there are pros and non-pros offering plugins and for that, I commend them. Heck, I often donate. KUDOs for a job well done and THANKS.
But, if you don't plan to keep your work compatible with the latest version of WordPress, why bother at all? Particularly for SEO, because these folks KNOW the effort involved with it and the importance of not having to "start over" after a year or two of said effort just because a plugin's author finally landed a big job and can't be bothered anymore.
Users are nagged on their plugins page after updates to the application -- that functionality is there for a reason -- and if you are going to keep offering your plugin, it needs to work with WordPress correctly and smoothly OR suffer a penalty by being dropped from the extend/plugins list...
OK, rant over and thanks for listening. I'm not a plugin author but I AM and have been for YEARS, a beta tester of major commerical software and so I know the effort and processes. I don't whine that often about this, but feel occasionally that I have to make the point that developers DO profit even from FREE plugins and should be personally invested in delivering the best product they can OR JUST DON'T BOTHER AT ALL.
