I think so. Give people a year or so to move over.

I'd prefer two years.  Not everyone is moving as quickly as GHC, and containers is a core library.

An alternative would be to see how many hackage libraries would build after e.g. one year if we removed the function. If there are any, wait some more, if there are few, remove the functions. I picked one year as that's equivalent to two HP releases.
