People who take security seriously do.
Just because you never had an issue doesn’t mean there’s no attack surface with an unlocked bootloader and root.
Due to the convenience I had rooted phones for years - without a single issue (that I was aware of).
Backup/restore of apps or phone, migration to a new phone is just so much easier with root unless you want to rely on ‘Google cloud’ for that.
But nowadays I value security more than convenience.
