just because I believe you have the right thought but it came across a little lacking on paper (we are all guilty of this from time to time) ----
String gauge doesn't matter on electric guitars because they have individual bridges that can compensate.
Acoustic guitars can be intonated by changing gauges. This means buying 6 individual strings (once the correct gauges are discovered), not a pack of 6 pre-selected sizes.
Acoustic Guitars are intonated with a file and either adjusting the existing sadle or cutting a new one. They can definitely be intonated its just a lot more work and not something you would want to do very often.
