> if you want to travel (outside of eu) you have to request a regular debit/credit card
The era where maestro cards were impossible to use abroad was already over ten years ago. The only thing you might need a creditcard for abroad is hotels and car rental, which you wouldn't be able to do with any kind of debit card (outside of a relatively small selection of hotels).
That doesn't match, at all, with my experience. I had to travel for work all over the world the past 8 years, usually twice a month and my maestro cards didn't work in any US atms or shops, nor in chinese ones, nor in hk, indonesia, australia, cambodia, most atms in thailand and other places.
In the US & China, it had big maestro stickers everywhere, but it didn't work at all. Different cards, different banks; on calling the banks they said they did not even see a transaction coming in and they the cards are set for international travel (and work fine everywhere they are accepted in the EU).
And it's not for lack of trying; One time on a big slog from US -> China -> AUS, I (stupidly) brought 1 credit card and 3 maestros and my CC got cancelled (fraud); I tried literally every atm , shop in these countries and could not get $1. I had to borrow from my colleagues. This is a few years ago.
