The goal of the modules was never for a 4th edition style character in the same campaign with someone playing OSR type character, the modules were meant to be basically the equivalent of character creation for the DM to design a campaign. I think you can see this in the first article where the modular goals were first announced:
"In some ways, you can think of this process as akin to character creation for the DM. The DM decides what kind of campaign he wants to run, in terms of tone, world elements and so forth, and then picks out options or rules modules that match that tone. The campaign setting becomes as much of a character in the rules as any NPC, location, or event."

I actually think the last playtest document that I read comes closer to moving some of this into more the player realm with the ability for PC Players to choose if they want to be more tactical with feats or choose an ability score bonus as well, but given that the feat module is optional it is still solidly in the DM's court as well.
