I'll chime in on this. I regularly use LRECL=259 for private PDS's when they need to be VB specifically to get 255 on any line, or to receive JES and other report listings where I don’t know the incoming LRECL a priori.
LRECL=255 is probably OK for any of my actual usage, I just prefer 259. If I were a vendor, I would probably "go along to get along" and use 255 if that's what the client(s) want. Not enough difference to take a firm stand on it one way or the other.

Clearly, the intent was to allow up to 255-character source lines. At PSI, we provide the option for customers to allocate our CLIST/EXEC libraries either RECFM=FB w/LRECL=80 or RECFM=VB w/LRECL=259. One customer claims the industry-standard for RECFM=VB CLIST/EXEC libraries is LRECL=255 rather than LRECL=259. LRECL=255 would allow for only 251-character source lines, which seems rather strange to me. Of course, my personal observations and experiences provide nothing more than anecdotal evidence. Like a man with two watches being unsure of the time, I am now unsure if LRECL=259 is widespread practice or if I was observing only outliers.
