I don't know that I'd go so far as to stay sticking valves was chronic with flathead engines in general, but it certainly was encountered with some frequency. Lots of possible causes, failure to properly ream the guide ID when guides were replaced, excessive blow-by, predominance of low-speed driving and short trips with cold engines, and the like.
Whether MMO or use of an oiler actually solves the problem, I suspect most of the evidence available is anecdotal. But in 1938 Packard did recommend a slight rework of the guides when the problem occurred, here's a picture from the 1938 service manual.
The oiler probably falls into the "might help, can't hurt" category.
