Eh. I’m not convinced by this. I may know what I want to query as often or more than knowing where it comes from.

I suppose it could be nice if the user could specify clauses in an arbitrary order but it’d certainly add complexity.

I don’t find it difficult to jump around a bit from clause to clause while writing a query. In fact, it’s incredibly rare to write a query straight through and have it do what you want it to do.
