Warnings for Exports w/ .xlsx that are over 100,000 lines is Gone - please reimplement

For the first 3 years at Domo there has been a warning about exports over 100,000 lines for .xlsx saying "there are possibly missing lines of data as you have reached the max data exported via .xlsx." The issues for us here is that people are going to be working with large data sets and then never know that data is missing. so, pretty frustrating that it is no longer a part of domo.
