So now as SEO, you have to follow the latest changes in Chrome, because whatever Chrome adds, it's likely that GoogleBot will also support it with the always green GoogleBot.
Ilya Grigorik of the Google team posted on twitter that the Chrome team has added native support for lazy loading to Chrome 76 and that means that when GoogleBot 76 is short, which will soon be, it will also support native.

Gary Illyes of Google asked Martin Splitt of Google to confirm that this would also work for the engine of GoogleBot rendering and Martin said yes.

John Mueller from Google has added some more context:
Well, of course, I meant the lazy part, I just didn't mention it because I'm lazy.

Again, GoogleBot is not on Chrome 76 yet, but it should be fast.
