Even that would be fine, we would still see that Representative Smith inserted the language into the bill. Its the person that has merge permissions into the main branch that has the accountability

This solves what, exactly? We already know bill sponsors, the provenance of bills is generally not a problem in the US. All the regulatory capture and pork usually happens in the open already.

I’d be less concerned with elected officials taking credit for “good” legislative language they didn’t actually draft and more concerned with a “language laundering” of sorts. By that I mean situations where the “bad” legislative language couldn’t be easily attributed to any specific elected official’s office because they’ve colluded to make successive, small, innocuous changes that, when taken together, turned in to “bad” language but it’s not easy to pinpoint which change, exactly, made the draft “bad”.

Even if the changed was committed by @OfficialComcast, a significant contingent of the temporarily embarrassed millionaires would accept this as the best course of action. After all those captains of industry are experts and probably shouldn't be questioned.

Captain of industry is an ironic name: a captain is typically someone that has been placed in authority by even higher powers, that's not typically how industry leaders like to describe their ascent.

Captian comes from the Byzantine latin word Katepano, while it can mean "placed at the top", there is no implications of higher authority placing them. Usual interpretations are that the person facually at the top how he got there is not really a factor. Somewhat akin to saying "boss" today.

Surprised by your downvotes. Getting into the club is a very social activity usually.
