You’d be surprised how little it actually matters. It just means they have to spell it for people occasionally.

My name isn’t common here, but it’s also perfectly well known and spelled in the traditional sense.
I have to spell it for people, and often use a middle name for takeout orders. That’s about the extent of the burden of having an unusual name.
My last name is also perfectly common, and I need to spell it as well.

I’ve seen a lot more “burden” on people with alphabetically late names, since they often are last in line for stuff.
