It’s good of you not to say the competitor’s name but you don’t need to worry about that in this community, Monzo isn’t worried about the competiton 
To me, it looks like the services related to international accounts / transactions etc. are Revolut’s main selling point, whereas at the moment Monzo is focused on building the core services that users typically rely on from a bank at home (but better 
). The fee free transactions & ATM withdrawals abroad are the obvious exception but it’s just one of the benefits & not always the primary selling point.
The good news is Monzo are testing Euro accounts at the moment & international expansion is definitely in their plans.
But it could be a while yet before they’re ready for that -
So while that would be a great feature to have, I wouldn’t count on it being developed too soon..
