Not MySQL, but with the MariaDB and MaxScale combo this has been possible for quite some time. The only drawback in my opinion is that you'll need a duplicate set of grants, one for accessing the database for the maxscale process and one for accessing the database as the client user. It is free to use for small clusters (3 node).
I've been a happy MaxScale user for a couple of years now, it is simple to configure and very robust.
I guess everything in the US is controlled by fear. So for them this might be a legit argument. "What happens if someone breaks into your house?". "What happens when somebody robbed you?". "What happens when somebody uses your credit card to do fraudulent transactions?"
Guess what, having a debit card in the Netherlands gives you protection against all of the above. Luckily not many people are ruled by scare tactics over here.
Lost your debit card for some reason? Just a simple click in your online banking app on your phone is enough to block the current one and recieve a new card the day after.
