I think there is a variant of "you don't currently need it" that people should follow more. Build towards what you think you will need, by all means. But try and only build what you need right now.
However, I do not like the readiness that people have with throwing around the yagni argument for things they don't want to support, build, or disagree with, often contorting or oversimplifying it to get their way.
The yagni argument itself is reasonable, but is often misused/abused.
