Hey, Kelvin from Atlassian here. We are pretty flat out ourselves improving both Bitbucket Cloud and Server. I can see how SSO isn't terribly important if Bitbucket is the only one of our products you use, but it's critical for our customers who co-own Bitbucket and JIRA (or Confluence, or HipChat, etc.). It was a fairly massive undertaking: retrofitting auth across our portfolio of products took some serious engineering effort. But we've still managed to squeeze a few fairly large releases out recently shipping features such as smart mirroring, Git LFS, and clustering - and have some other great stuff in the pipeline.
