Is third-person omniscient dead?

So, I'm writing a romance novel in third person omniscient, present tense (did I fly too close to the sun?), and the feedback I've been getting is that my readers want to get closer to the MMC and FMC, that my perspective is too objective.

This was kind of my intention when writing this book in that POV, but readers telling me to shift closer to third person deep pov is exhausting. My inspiration for this novel was a historical romance novel written in third-person omniscient. I know there has been a shift in publishing to put out more stories in first-person POV and third-person close writing, but I've given up writing my book to market.

Anyway, has anyone found success in writing in their particular genre and breaking conventions? How have you done this successfully?
