At this point this is the released version since it already has to be loaded into new 5C and 5S phones.Even GM's can be changed...
Actually it does matter if you intend to sue anybody over a version which you are not supposed to install unless you are a developer, which implies you can expect some issues.
Besides that most complaints can be solved by resetting all settings, or are related to slower devices. Some are genuine bugs which need to be addressed by apple, which i'm sure they will.
If you don't like 7 just go back to 6 and stay there or wait for a 'better' 7 version.
A lot of these animation items are actually not related to the install or settings or performance, but to the simple fact that Apple made animations longer in iOS 7 pretty much for the looks of it all (at the cost of some usability/productivity).
As for suing, the OP makes it pretty clear that it's not what it's going for.
