I think that admonition is for advanced users. If they are mounting with these
options, then they know what they are doing. The warning just means that we do
need suid executables, devices, and access time when building.
If a user doesn't know what it means, then there's no harm, but we have regular
problems with users who think they know a lot and start 'optimizing' right away
and then have problems.
The paragraph is useful for some users.
