That happens. My point is that you're responsible to your customer to deal with deviations from their spec. Don't bother with substitutions until you know how your customer feels. You can waste a lot of time (In 40 years I sure have) evaluating how someone's substitutions impact your project when the only accomplishment would be doing someone else's work or helping to make their sale.

I used to think this before I learned how and why to ask questions. Unfortunately there are a lot of silly questions, technical and otherwise. For example, any question is silly if the questioner isn't prepared to evaluate the truth or sincerity or usefulness of the answer. Questions which have no answer or are phrased to allow ambiguous answers are the equivalent of silly questions because they can result in behavior associated with silliness. Technical questions especially may silliness if they aren't clear as to what the answer is meant to accomplish and what's riding on the answer.

Which is not to say that your question was one such--only that it appeared that you wanted someone to justify the substitution, without first knowing whether the substitution was even permissible, let alone technically advisable or economic. Instead of 'stirring up discussion', you should be asking what's in it for my client, then what's in it for yourself and what's in it for the vendor.
