We did it several years ago in GA. Had to show birth cert, two utility bills (to show residence) and/or bank statement (with street address). If your name changed after marriage, you had to bring the marriage cert.
The only difference on the drivers license is the addition of a gold star outline in the upper right corner.
I don’t see any personal security issues with it as the very same information was available before “Real ID”. The only difference is that now your address is proven/verified.
So why jump through the hoops? The only thing I can think of is that, here in GA, we have to show ID to vote in person. The Real ID *could* help prevent non-citizens and non-residents from voting. I stress “could” because after the sham election in 2020, GA utterly failed it’s residents and the nation. We had to show ID when voting in person, but it was not required for the mail-in/absentee/drop-box “goat rodeo”.
