Many Authors: Insufficient Field Length

I have an article with many authors, this is common in science. In this case this is something like 650 characters. I know how to change the size of a field in the database but the Authors field in bib table cannot be made larger than 512 characters. Why? How can I increase this to 1000 or what is an alternative way to do this?

In the next version 11 minor

In the next version 11 minor upgrade, we will allow the string field length to be changed between 1 and 1024. That will meet your needs.
