☂️ 👣 Breaking changes for v7

[patrickhulce]

A collection place of breaking changes we'd like to make in v7 that might not deserve a separate issue. If you come across any API that would be nice to change, add it here :)

If the list never gets long we can convert of close in favor of a regular v7 burndown list once it gets closer.

Targeted

• ImageElements: update artifact shape Update ImageElements artifact #11642
• nodejs: drop support for Node <12. misc: drop support for node 10 #11656
  • Will get us Intl.NumberFormat units!
• details types: split node details to subproperty core(artifacts): encapsulate node details in an object [reverted] #11474
• axe-core: update and evaluate all the enabled checks core(a11y): upgrade axe-core to 4.1.1, update a11y audits #11661
• fullyLoaded: wait for images for LCP (possibly more?) Lighthouse doesn't wait long enough for page to load (NO_LCP) #11180 Performance test is finished in the middle of page load (waiting for an XHR) #11639

Perhaps v7

• consoleAPI entries in ConsoleMessages artifact Gather console.warn, console.error messages #11597
• emulation: shift around emulation flags Reconfigure emulation flags #10910

Punt to v8

• possibly recalibrate throttling multipliers? Improve BenchmarkIndex to land device targeting #9085
