Don't add extrema in TrueType export

Is there a way to prevent extrema from being added when exporting a font as TrueType?

Making TrueType curves without extremes is tricky. And you will get problems with different algorithms calculating the bounding box.
Why do you need that? Can you give an example?

Hello, Iā€™m trying to do this too because the ttf export creates minor kinks. (increasing the upm helps but does not solve every instance). When I convert the outlines manually from Paths>Convert to quadratic, the resulting conversion is perfect, but when I export to TTF, the extremes mess up tricky curves like this oneimage

Here is a conversion result from the Path>Quadratic it looks great. Is there a tool that would help me get an export without the extremes?
