I'm fine with making applyUpdates default to strict mode to make it consistent to other parts of the codebase and encourage people to use the strict one which does not have extra overhead on scanning the CFG.

But if the user follows the rules on using applyUpdatesRelaxed/Checked, DTU is also guaranteed to have precise information on updates.
