This is very cool to see, and something that should have been at the heart of the EU monetary union project, we're it to serve "the people" and not just "the corporations, in the hope that trickles down". Very similar to the just unjustified and unnecessary (and hopefully soon to be gone) telco cross border BS.

Of course, if the cost of currency exchange is estimated, it won't necessarily solve the problem I faced transferring money from a German to a Swedish account to pay my rent at the time: not knowing exactly how much of the sent money would end up arriving, and how much would be used up for fees, I had to resort to other payment services with much higher fees... This is purely a UI problem of the banks I tried, but that also means apparently the almighty market does not give them enough incentive to solve problems that are not those of rich people. Who'd have guessed.
