Simply because there will be a "better combo". And if you want to make choices that impact your DPS depending on the fight (For example reducing X cooldown by Y seconds which would be helpfull in some cases), people would be tired to switch everytime their "BiS Talent".
Utility wise:
We had something that involve making a choice for role skills. They ended up making everything available because too much was needed for healers and everyone choose the same utility for DPS/Tank.
Status effect in battle already exist and that's called Silence/Stun. It's used in E8S and every job has to use their utility, unless you're healer(non-whm)/caster. Snare was also used in Coil (I think never played this content) but damaging the target would remove snare, Sleep suffers the same problem and Paralysis is a stun RNG based.
Also I was curious when you said raids were DPS fest so I allowed myself to check a bit what kind of content you use to play... And looking at your achievements/mounts, I don't think you play Extreme/Savage content? Mechanics are in these difficulty, every other content is a DPS fest you can barely fail/complete with only tanks/healers.
However, this kind of content could work somewhere else than raids. For exemple Eureka-like content. Logos are a kind of a choice.
