Without enabling LTO by default it'd double (or triple as LTO builds are
longer) the amount of pre-commit testing. ports/ committers have to test
changes on their own hardware as poudriere requires root which universe*
machines[1] don't provide. Without poudriere[2] testing is fragile and hard=
 to
automate, so would likely trip on complex desktop ports with many dependenc=
ies
(like www/firefox). Some folks experimented[3] with offloading testing to
third-party CI.

For example, SNDIO used to break often until it was enabled by default.
