When I created CNC cutter paths for a mold shop I would scale the model up by the shrink factor before subtracting it from the mold halves. So shrink was essentially "built in". I would do the same now for the FDM printer but it hasn't been an issue even for close tolerance details I've printed in PETG or PLA. If they sit in the sun they expand and if they are in an air conditioned environment they shrink.
The setting isn't available for my Creality machine, and although I've thought about it, I haven't found a need for it. Yet.
When printing with Polypropylene I have to add 1% shrink factor to get close enought end dimensions. Otherwise I don't use it. I mostly adjust the horizontal expansion to get precise dimensions.

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.
