The question of positional control is interesting. The mechanical stability SL provides comprises a system of muscular effort that is a separate thing from sound production. It doesn't necessarily interfere with sound production, but there can be overlap if one isn't careful or aware, especially in the use of the jaw (i.e., biting etc.)
Playing SL, I was formerly somewhat of a biter, and I needed a mouthpiece patch to protect the mouthpiece. With DL, that went away, and an unexpected side effect happened. My tongue noticeably freed up. Apparently the varying tension in the lower jaw had been also expressed in the tongue, since the two are physically connected. Again, that wouldn't necessarily be the case if someone was careful and aware enough to avoid it. When DL forced my lower jaw to relax, it stabilized to a degree, and my articulation muscles seemed to clearly appear as a separate system for the first time. My articulation rather suddenly improved. That was an additional benefit alongside the sense of a more intimate feel for the mouthpiece that DL gave me.
