Nah. I have hosted my domain for 17 years on google and then fastmail. The hosting is harder than private relay, although not too hard.
But I have only had maybe 3 services ever reject my domain, and those were because the domain contains a number.

I have since stopped doing this out of fear that it will actually cause me more headaches with people/systems that don't understand how email works.
What a load of pedantry.
