Yeah generally even a coasting employee is doing some minimum amount of work. If burnout is a concern it's actually better to hire someone with the intention of PIPing and kicking out the coaster after. Since the coaster has been there as long as they have, a bit of extra time won't really change the situation.

[Note: This is WILDLY different if the coaster is actively generating more work for peers. I'm talking producing mediocre code that needs extra code review or not completing assigned tickets forcing peers to pick up that slack to finish the sprint. Get the team's opinions on the situation in 1:1 and boot ASAP if folks find this is a source of friction for them.]
