How do you know? Maybe its used a lot but the users had no need to tell you
what they were using. The exact opposite might in fact be the case i.e.
because concat is so good in splus, you just never hear of problems with it
from the users. That might be a v

phew! had me worried there.
c() is no problem at all for lists, Dates and most simple vector types;
why deprecate something solely because it doesn't behave for something
