Bvars from hashtables have always worked as they currently do -- all data from the hashtable item is added to the bvar regardless of length -- but I seem to recall there being an issue where, when outputting data from a bvar, instead of raising a line-to-long error the text was truncated.
I can't remember if it was related to /var, /echo, or some other output command but will look to see if I can find the report and documentation of the subsequent fix.
