It's honestly ridiculous, I thought we were past it after Edward (and honestly, him flushing the 'coven of Rosies' including the 'posh blondes who tousle their hair a bit and think they're the next Anita Pallenberg/Stevie Nicks' types off the magazine pages was one of the better aspects of his time as EIC) but we're right back to it? Nothing against Suki or her relationship/offspring, but it wasn't interesting then and it isn't now.
If they wanted to be lazy they just can do yet another Kate Moss cover - WITHOUT her dead-eyed nepo kid as a package deal please - that would be preferable, at least Kate can pose. And it's madness to me that Charli has never had a cover despite being an actually brilliant and impactful recording artist (even pre-BRAT), being British, supporting British designers etc.
Even if they wanted to go the 'representation' angle with Charli, she's mixed-race on top of it (not that she ever needed to tick boxes to be worthy of a cover, she deserved it as an artist, period). Missed opportunity but not surprising considering the creativity deficit you described.
