Mathematically speaking, isn't it true you can compute the coordinate transformation (with your choice of map projection, perhaps ignoring the poles)? The real problem is that your metric / notion of distance has changed, so you can't simply compute distance as sqrt((x2-x1)^2 + (y2-y1)^2) and expect it to map neatly to a circle on the globe.
This is very common in Germany. I worked (and work) with several people across different employers that worked 2, 3, and (this is the most common variant) 4 days per week. All folks that worked 2 and 3 days, in reality though worked 7 days, because they were working on their personal project.
the law (or a more employee-friendly change to the law) came to pass last year (2019). The law gives employees much better chances to follow through, because it's now up to the employer to prove that part time is economically unfeasible for the employer. Before, if you wanted to go from full-time to part-time it was much more about hoping that your boss was understanding and having to argue etc. (although women with children usually had very good chances and usually in Tarif-Verträgen it is included that they can do part-time, so in big industries/companies it was easy for women already, at least those with children). I think in the Netherlands part-time is even more common; I've read somewhere that 50% of the people do part time - and most of them (unlike in the US) do it because they want to (80% of women there work part-time; 20% of men work part-time, so as a whole 50% do).
The author puts a lot of work towards making this proposal a reality (as far as I as a casual twitter/slack observer can see) and I'm looking forward to it.
Unfortunately, the proposal has been stalled by the C++ committee and the author is uninterested in continuing it. See their post here https://thephd.github.io/full-circle-embed
This is similar to idx/sub files from DVD which are just images and they are OCRd to text sub/srt file. I assume it's just easier for them to render the image than to mess up with text rendering/code page issues/whatever complication coming from huge diversity of devices they support.
