buffering moves in VF4

can moves still be buffered in VF4? below are examples involving Lion. Thank you in advance for your feedback. (zero opportunity to get to arcade until weekend).
d+P+K, with a buffered d/f+P -> d+P-> D_f+P, (if blocked) -> u/f+P+K+G-> d/b+K, and f+P in theory look viable for good play book options.
d+P+K -> D_,f+P [float] -> f,f+K,K
d+P+K -> df+P+K+G or ub+P+K+G > d/f+P> d/b+K
d/f+P -> -> d/b+K -> d/f+P -> d+P+K (see stuff above)
