BUR #10098 has been rejected.
create implication standing_split -> leg_lift
I think ~900 posts under standing_split leg_lift solo compared with 3.25k posts with standing split solo (roughly 28%) is a considerable number.
I also couldn't find any visible obstacle under standing_split -leg_lift yet, I'd argue if leg lift isn't supposed to be used with standing, then 2.1k posts under leg_lift standing solo is a lot to garden.
