> A major difficulty to note with Meta viewport and keeping a 
consistent width at screen rotations e.g., is that it requires a 
calculation of the new expected scale ratios according to the prior 
orientation and respective screen sizes.

Note too that "consistent width at screen rotations" is not always 
desirable, but is definitely something the author wants to control. 
For the sites I work on, it is more important for the scale to stay 
consistent when the device is rotated, so that rotating can reveal 
wider areas (longer lines of text, images that are wider than the 
width of the vertical viewport, more table columns, etc.). For other 
sites, scaling is better when rotating, so that e.g. text will be 
larger and more readable on fixed-width text blocks (you can fit the 
whole line of text to the larger dimension of your phone just by 
rotating it).
