Big no. On the open source projects I supervise which have a fairly big reach, it's simply impossible to do that, especially since I work on it a few times at night each week. Having office hours would mean dedicate even more time to them, which I can't. It would mean speaking in a common language, probably English. Writing in English is one thing - talking in English is another. It's super tough for some foreigners (including myself). It would also mean much more organization. Calendar invites, Zoom or whatever tools, etc...
