I would prefer the prequels be referenced occasionally, though not in a way that would dredge up any of their continuity issues with the original trilogy. For example, no references to Qui-Gon as Obi-Wan’s master, since in the OT it was Yoda who trained him. Featuring Bail Organa as played by Jimmy Smitts is perfectly fine, being a character referenced in the OT and nothing about his prequel portrayal strains this. I’d rather not reference Threepio being built by Anakin.
Y’know, reference and include the prequels to whatever degree is appropriate, but I’d avoid anything that wouldn’t read well if one hadn’t seen them.
