Changing this threshold can have a significant impact on code size. Artificially boosting the outlining 'benefit' can, in many instances, actually regress the size of function-undergoing-extraction (defeating the point of hot/cold splitting). Could you share some data, specifically:

- Which projects were tested, at what optimization levels.
- Code size, pre-patch vs. post-patch.
- Code size (non-extracted functions only), pre-patch vs. post-patch.
- % of functions which undergo hot/cold splitting pre-patch vs. post-patch.
