What's the current status? I'm just pinging it because it's targeted towards M-62.

Code is done. Waiting for UX decision-making. 

Since it was not enabled on M62 Canary/Dev, M63 is the earliest milestone we can roll this out to.

Did this happen for M63?

No decision taken, yet. It is on my radar.

[Ntp Tiles] Decrease the threshold for real icons to 24px in Modern

This CL changes the threshold for showing real favicons (instead of
"scrabble" tiles) for NTP Tiles in Chrome Modern UI. In Modern, the
icons take half of the space as before (24dp). After this change, the
threshold is 24px, also half of the previous non-Modern value.

The previously used feature NTP_TILES_LOWER_RESOLUTION_FAVICONS is not
needed anymore and will be removed by a follow-up CL.

[Ntp Tiles] Remove an experiment NTPTilesLowerResolutionFavicons

This CL removes an experimental feature and a corresponding flag from
chrome://flags. The removed feature was not needed any more because
the behaviour is now enabled by default if ChromeHome is enabled.
