[infinispan-dev] Repeatable reads and WSC as default

Hi all, I am writing a bit too late in 9.0 cycle, but since I've found couple of bugs [1][2] and spaces for improvement [3][4] in WSC implementation, I was wondering about confirming the performance effect of fixes. And I am wondering if the current defaults for transactional cache, being READ_COMMITTED and WSC off are the best options. During 8.0 cycle Tristan raised a discussion [5] including WSC defaults and I think that the general opinion was "make it default", which requires RR isolation and simple versioning scheme. But I think that the whole thing [6] went a bit forgotten and all that was done is [7]. Do we want to do this, at least using current API?
