No drain with POWs. There is at least a chance that the truth of the encounters escapes into public knowledge. You require parole of the crews (who might be smart enough to refuse further combat anyway, that's a PR hit.) And then the SLN [idiots] maybe waste their resources in the same way it has been suggested here, trying to fix them.
Parole would be difficult to arrange. Terms such as 'parolees can't be assigned to positions that would return them to the conflict until/unless exchanged' won't work, since the GA should be launching deep strikes into the League. That might be manageable; e.g. 'can't be assigned to hypercapable ships until...'.
But the big problem is that parole assumes a degree of good faith on both sides. I.e. that parolees won't simply be ordered back into the war. Which would put the parolees in the position of either violating their parole or disobeying a direct order. The SLN would have to publicly agree not to do that. But the Mandarins are currently claiming that the Manties murdered a million Sollie spacers — after they surrendered. How can they agree to treat the Manties as honorable enemies?
If they don't, what are the Manties going to do if they recapture parolees violating their paroles? Shoot them? PR-wise, it'd be better to keep them as POWs, and eat the cost of their rations and quarters.
