     108Q & A
     109
     110- What architecture changes are associated with Turbo DFG
     111    - Open to different ideas: first will be removing the baseline, definitely a possibility of a 5th tier, first replacing baseline
     112- Finishing unified builds: will there be a bot to verify non-unified will still operate?
     113    - No specific plans, but a worthy idea
     114- Native dev: WKWebView for Media Applications?
     115    - Many apps that use WKWebView want to control how media playback works
     116    - About control of video in a web view
     117- How do you decide what’s important to do next?
     118    - We look at a number of factors
     119    - It used to be a judgement call, now we’re codifying
     120    - We look at a number of signals
     121    - How much dev interest?
     122    - is there a harmful aspect?
     123    - WPT areas are similar:
     124        - Most tests failing in Safari, but not in FF or Chrome
     125    - Sometimes we use high-value websites
