As part of #4642, @RonakLakhotia added an integrity check for books with an edition value of "1". Since the official biblatex manual (http://packages.oth-regensburg.de/ctan/macros/latex/exptl/biblatex/doc/biblatex.pdf) suggests the use of the integer "1" for marking the first edition of a book (see bottom of page 18 in the referenced manual), my colleagues and I typically follow this recommendation. As our database is quite large, this results in lots of (in our case not useful) warnings when performing an integrity check. Would it be possible to make this check optional and decide about its execution based on the user's preferences (by default, it can be enabled)? Many thanks in advance!
