Is it normal for retailers to sell EBMM guitars manufactured several years ago?

I’ve been on the verge of purchasing an EBMM JPXI-7 guitar for months, now. I finally went to pull the trigger last night, but after searching up the product serial (to ensure it is legit), I discovered that the guitar was manufactured in July 2015. Everything sold on this retailer website appears to be brand new unless blatantly specified. So, does anyone know if this is completely normal? Perhaps EBMM last manufactured a bulk of JPXI guitars in 2015, and still haven’t sold them all? Was it lost in a warehouse? I hope this isn’t a dealbreaker as it is my favourite, but other candidates are a JP-7 BFR ruby flame (manufactured July 2019) and a JP15 BFR eminence purple (manufactured late 2018). The XI is my favourite, however.
