No half measures
That's really not the point though. The issue is that Stone being on LTIR until day one allowed them the space at the deadline to add two impact players that are now on their roster. Had the expectation been that Stone would play before the end of the year they would not have been able to add both players without subtracting something significant from the roster.
Set aside the legitimacy of this specific injury. If a star on a contender misses games 10-30 in almost every case the only reasonable option is for the team to replace the player internally with one or more players that are substantially below the star in impact. In this situation that team not only has to deal with the in-season fallout from there missing star but they cannot accrue cap space for the deadline, and they definitely does not give them a stronger roster for the playoffs.
In contrast, if the same star is suddenly out from the deadline to the end of the season, that team can use the cap space to go out and find an impact replacement from outside there roster, and because of the unique timing might even be able to leverage the space into two impact players. So not only do they not have to deal with the drop off from a star to an internal replacement in the regular season but they could in theory get stronger even without the star. Then the player comes back for game 1 and you have a team that is significantly stronger than they would otherwise have been at the most consequential time of the year. This is what makes it so tempting for a team to abuse the LTIR rule.
No it's exactly the point. Using LTIR to filling the roster while guys are out long term is intentionally allowed and every team does it (13/16 in the playoffs this year). That isn't abusing LTIR, that's using it as it's intended to function. People are bitching about Stone being activated to gain an advantage of being over the cap in the playoffs and here they are not being over the cap.
