Pretty much everyone has a gLinux workstation or logs into a gLinux VM - they were, traditionally, the only devices that had access to the main source repository, so it's not so much about whether people want to or not.
Googler and ChromeOS engineer here. Opinions are my own, etc etc.
This has changed/is changing. It heavily depends on your team (especially if you're not in engineering, I don't think most non-engineers would have a gLinux machine or a workstation out of the box). We've developed tools for crostini that would let people access a gLinux environment, I don't know how much I can talk about it so I won't go into details (although it's nothing super secret either), but the bottom line is that more and more engineers these days are able to do 100% of their job on a ChromeOS machine, including dealing with google3 stuff.
