We do, we have, and we will always improve on SEO as things change. What most don't understand is google and other search engines are an always changing item, their goal is to find what you are looking for , as site owners often hack their way around into fooling/tricking/seo'ing google and others to list their site higher without actual valid "high rated" content, google and others are always looking for methods to rank content properly, and see their way past the tricks people play, they will in time find a way to de-value the bad content and rank appropriately. If you want to rank high for something, you better have high value content on your site, that is the bottom line, if you do, you will never worry about SEO again.
Here is some insight, if this will help, I have been a big proponent internally of the back to top button, because I use it everyday, on all my communities, it's the way I browse, some may call this silly, some may agree, but change is hard for some, and when it's a forced change it makes it tougher. It's like a cup holder in a car, some may never drink in their car, some would hate for it to be gone as you may use it everyday. This is one of those cup holders, sure you can go buy a cup holder that hangs from your window, but it's just not the same, while in a perfect world there would be a simple option to turn this on or off, however there are many more important things for the team to focus on currently. There will be many solutions, there will plugins in the market place to add this back once 4.0 is released, so for those that use it like a cup holder, wait for 4.0 final, and it will be available. I personally plan to have a plugin available for my own use and will be posting it in the marketplace, there are others working on variations as well.
