What looks good for career advancement? Talent management is not an end-job, it's a stepping stone. Everyone knows celebrityhood is fickle.
Merch releases, con appearances, launching new branches, fan shops - anything that looks like it stands out - all these are distinct points on your resume to talk about in your future interviews. Same shit with IryS, saying you personally spearheaded, drove, and directed all the music projects sounds much better than 'facilitated talent in accomplishing vision'. They want the credit and involvement regardless of end product quality.
On the other hand, no one cares if you write 'presided over talent streaming X hours a month'. Your contribution is minimal. No one cares if you wrote 'obtained X permissions'. That's expected, it's part of your job. It's actually worse for you if the talent streams more, because more streams equals more chances for them to cause a PR disaster somehow and more work for you. It's not like you get paid more if they get paid more either. At most you qualify for a bonus you would have qualified for anyway. So it's in your interest to reduce their public exposure and increase the number of behind-the-scenes projects. Even better if they don't come out so you can talk about your valuable experience working on them and how good they would have been without being challenged by reality.
