I totally agree!
The frisket is way too agressive unless the previous finish is completely cured, which can take days for some paints. I had to do much repainting myself on a recent camo scheme because of that same frisket problem.
I've since gone to Post-It notes. They release easily, give a good crisp line, and I can do multiple colors in the same evening. Much cheaper than frisket, too. Their only drawback is that they tend to lift on the ends, but I've found ways to keep them down, at least until the paint is sprayed.
Tamiya tape is also good, but I have to let the previous coats dry at least a day before using them.
Good idea to put the warning out there.
