That's a good question but not one you could answer easily without proper research into your chosen market.

If I was to speculate though I think you'd possibly find that you have long tail of potential customers spread outside of the G7 countries.

That's leaving out that there are a lot of very wealthy non-G7 countries.

To me the real key here is making multi-datacenter instances easy, whether those are multiple datacenters in the same country or 37 countries.

But even to stick to your question, the G7 spans probably a dozen time zones. Even if you stuck there, you'd still have a pain with a multi-region app and see benefits.
