Thanks for the fast answers. I am aware of the scaling method as I mentioned in the original post. I have to say this is a very impractical workaround that many people are forced to do. High number of polys in small objects might be impractical in 3d-printing, but that´s their responsibility when designing (most people print their own designs so they will quickly find out if they cant be printed properly). Also, the limitation doesn´t stop anyone from doing the high poly, just takes more time because you have to scale up and down all the time, also re-enter the circle setting that gets resetted. In the end, you end up spending 10-20% more time on the design… I have been using a 3d-printer for a year and never had any problems with my designs, even with the upscale/downscale method.
Button line is I think this limit is just doing a lot more harm than it benefits the 3d prints. It should be user selectable, also there could be warnings. Think you should make a poll, at least.
