Plural .com with a developed singular — still worth holding?

A plural .com can make sense in some categories, but the singular .com being developed changes the picture.

Would you still hold the plural if the wording is natural?

Any examples where the plural still got real buyer interest?

I don't know of any site with plural domain names that I use.
