Direct method to define the maximum feedrate of a sequence

Defining the tool to slow down on internal corners isn't a problem. We do this when constructing trajectory passes using the arc_feed and arc_feed_control parameters

What I would like to be able to do is to limit the feedrate if it tries to increase dramatically. I figured if there was a parameter that could limit the maximum feedrate, no matter how much the tool/part geometry combination wanted to increase it by

Looking to limit the situation when a cutter is machining a very small external radius, and the toolpath feedrate multiplies hugely to maintain the correct surface feedrate.

For example - a profile finishing pass which is also base-cutting

If a 10mm endmill has a standard feedrate set to 1,000mm/min, but when wrapping around an external radius of 0.5mm with arc control on, this feedrate would increase to 10,000mm/min to maintain cutting conditions on the radius. (For argument's sake, we need arc control on to profile internal radii too) But we would want to avoid the full increase of the feedrate to avoid poor finishes from the base of the tool.

If there was a MAX_FEEDRATE parameter, this could be set to, say, 2,000mm/min in order to limit the increase in this specific situation???
