I wonder if it may be possible to distinguish program or human changing
the size. In most cases, when a program (in this case:
temp-buffer-resize-mode) changes the size, it is hardly ideal to keep
that change. But I agree that for example, if a user drags the calc
window to be bigger, it is desirable to keep that change permanent.

At the moment I have to have (setq calc-window-height 7) at my finger
tip to get rid of the size change sometimes accidentally happens.
