It depends on an org's priorities and what gets put on someone's reviews.
During one of the years when I worked on Windows Mobile (before Windows Phone!) we had an objective handed down from on high that we were to spend so many hours a week on customer support forums helping people out.
Well, for that year, customers all around the web got great support right from engineers! I got to paste lots of positive feedback from end users in to my yearly review, and I felt great about it!
If Google cared about supporting Flutter as an Open Source project, they'd make the health of the open source project one of the measurements going into employee reviews at the end of the year.
