With PR #106965 now made obsolete by the merged #113706, this PR is no longer necessary to achieve the goal I was after. (Re)-computing instead of storing the call frame sizes (which this PR does) might however still be worthwhile to avoid errors caused by missed updates of call frame sizes.
Let me know if there is interest in still pursuing this PR, otherwise I will close it.
