A whole lot of what you see in the "Lost Scene" is retconned into the thing to establish more continuity within the Askewniverse.
Alyssa. "Finger Cuffs." Truth or Date
. T.S. Quint. The images of Loki and Bartleby on the death announcement cards for Julie Dwyer. Which is all cool and it never bothers me. It's not as if Kevin knew who or what any of those were in the winter and spring of 1993 when he first shot the original Clerks,
and it only helps flesh out his universe and gives it more depth.
If retconning works, I say go ahead and do it.
