It's worth considering that there's still a chance that the cuts end up being more limited than proposed.
Kind of like the tariffs or the Tiktok ban that's totally going to go into effect after the most recent extended grace period ends.
So it makes sense that the current raises aren't big enough to make up the shortfall. They're aniticipatory in nature, with the assumption that the actual cuts will be a lot less crazy, and increases to take advantage of a talent exodus will take some time to ramp up.
