That should not be the case, provided that your rim is drilled for a 2:1 pattern? If your rim has the usual drilling with alternating holes angled left and right then it won't be compatible with 2:1 lacing, because that obviously requires 2 holes angled to the DS followed by 1 to the NDS. But I'm assuming you know that.

Something I noticed is that on the rear wheel, I have pretty much dead-even spoke tension across both sides. In my mind this seems desirable, no?
Yes. That's exactly what you want. And 2:1 lacing was invented exactly for this purpose. On a traditional 2crossed rim brake rear wheel with let's say 12spokes on each side, you'd get as little as 50% or less of the spoke tension on the NDS compared to the DS. Particularly with aluminium rims where usually the max spoke tension must not exceed about 1200N, you'll get less than 600N on the NDS. That's low enough that the spokles might detension themselves over time when the wheel hits potholes etc. With (high quality) carbon rims the spoke tension can be higher. I've built wheels with spoke tension in the 1500N range. That makes detensioning less of an issue. With carbon spokes the tension is even higher because those are not as elastic as steel spokes so they need to be tightened to crazy high tensions.
