IIUC what the intention is, it assumes that the user wants to fit the buffer to
the window and not vice versa.  In my case (dedicated window in a separate
frame), I do not want the buffer display to expand to fill the window.  Instead,
I want it to remain as compact as practical, and I then fit the frame to the
buffer.

Since there can be different user preferences and use cases, can you please
provide for those too when designing such a change (e.g. for the default case)?
IOW, let's not just assume that the window size is to be fixed and
predetermined, and that the buffer text should be fit to that window size.
