I don’t mean to dismiss this either, but I am curious as to what your experience is that you’re so confident in this (i want to be clear that I don’t intend this to be a jackass response, I’m just curious as to what your experiences are).
I’ve been working in the federal space for the last 9 years (can’t believe it’s been that long), and most of the bids my clients put together, whether as the prime or as the sub, are jointly done at the proposal stage. Lately, I’ve been working with a client for the last 2 years and been assisting with their procurement department, and have seen them run RFPs where their bidders include their subs in their proposals as well.
Now, granted, based on my client mix (don’t want to get into that here publicly), it’s very possible that this is just experience-driven and we both have our own legitimate reasons for our opinions, but I do want to make it known that it does, at least sometimes, go the other way.
