Most developers won't pretend they operate in the EU because that would likely result in account loss. As for anyone actually moving there for this, I highly doubt it. Most developers who distribute on the App Store are looking for profit, not creativity. Trying to go around Apple for this sounds like risking those profits.
Furthermore the European versions won't be available outside of Europe so if anyone wants to keep their existing non-European users, they'd have to maintain two versions. That's extra work and unless there's some significant profit unlocked by the European changes, the most likely scenario is that developers would stick to whatever's allowed worldwide. Which is likely Apple's goal - comply with the regulation, while making it sufficiently undesirable for developers to change anything.
