Eek, that's horrible. Please add a way (macro) to disable this.

Calling sync() hurts very much for big servers with huge disks and a big buffer cache. I get that's it's somewhat acceptable for software installation on the server (syncfs would still be much nicer so that data partitions don't get synced). But what you're forgetting is chroot installations like done by mock or container package installation done by dockerd.

E.g. this would severely slow down open build service workers.
