When I started in this business it was unheard of signing an exclusive deal without front end money. Now it's the norm, but I know a lot of writers that still won't sign those types of exclusive deals, and that's ok.
Will more production companies start asking libraries for a cut of the writer's share? Absolutely!. (Some have already been asking them for 50% publishing). Is if fair? "NO", but the business is constantly changing and like the song says, "You've gotta know when to hold em or fold em"...
This is not a one size fits all industry. I write well over 300 songs a year so I use multiple avenues for income. Everything from straight up non-exclusive licensing to WFH and everything in between.
I'm not advocating that writers sign these types of deals where you give a portion of your writer's share. If it were up to me, I'd love to see every song added to a library's catalog get paid up front plus back end royalties. But for now the deals I've done have worked out for me. Your mileage may vary....
