The problem I'm having with OP's issue is his contention that it nullifies social talent choice.

I, personally, disagree. I have maxed out persuade on my avatar, maxed out loremaster on my elf, maxed out barter on another character who does all my trading, and maxed out theivery on another who unlocks all doors and chests.

Would you say that kind of build nullifies choice? Because not once have I felt compelled to "go back and try again" or something.

Sure I could change my avatar to full lucky charm during dungeon crawls and my barterer to full sneak between barter sessions, but let me tell you... I am far too lazy to go through all that effort.
