DELAY() used to be only : available in the (cold) case in the past, but after reviewing the : function now, it didn't seem to be unsafe to use in the (!cold) case : to me now. (The man page for DELAY(9) doesn't mention any restriction : either.) DELAY is always safe to use. However, it is highly undesireable to use it for large values if !cold.
