So you leapt from "This didn't break the shit out of my computer" to
"everyone should do it this way". Creative. But wrong.

NO. If you don't have reason to retain the EFI partition (i.e.,
multibooting), just pick whole disk GPT and quit wasting time.

If you don't know what is in your EFI partition, you SHOULD overwrite
it so you know you have a clean and trustable system.

OpenBSD is designed to be able to install on wiped disks, new disks,
or co-exist with other systems. You seem to think that if you go
out a buy a new hard disk at the store, you couldn't possibly
install OpenBSD on it because there's no existing EFI partition.
A lot of people can assure you this is incorrect.
