For one thing, stats and the like can be slower since things like executable
permissions have to be determined by inspection.  But there are other mount
flags that can help with that.  So, there are trade-offs.

Yeah, sorry.  I glossed over that.

$ getfacl /
# file: /
# owner: lhall
# group: ????????
user::---
group::---
group:root:rwx
group:SYSTEM:rwx
group:Users:r-x
mask:rwx
other:---
default:user::---
default:group::---
default:group:root:rwx
default:group:SYSTEM:rwx
default:group:Users:r-x
default:mask:rwx
default:other:---

The group ownership is fine.
