I did experiments and found that for very small parts speed affects overhang quite a bit but for large parts it doesn't. It turns out cooling is very important where there are overhangs.
So maybe a better feature would be the current "minimum layer time" but have an alternate, slower layer time for areas with overhang. But really the two numbers are probably 5 seconds for vertical and non-overhangs and 10 seconds for parts with 45 degree or worse overhangs. This is a feature that isn't really needed that much as I assume most people usually print larger parts that need more than 10 seconds per layer most of the time anyway so just upping the existing min layer time to 10 seconds might be all we really need.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
