Maybe you missed this section:
http://blog.languager.org/2015/03/whimsical-unicode.html#half-assed

It lists some examples of software that somehow break/goof going from BMP-only 
unicode to 7.0 unicode.

IOW the suggestion is that the the two-way classification
- ASCII
- Unicode

is less useful and accurate than the 3-way

- ASCII
- BMP
- Unicode

Personally I would be pleased if 𝛌 were used for the math-lambda and
λ left alone for Greek-speaking users' identifiers.
However one should draw a line between personal preferences and a univeral(izable) standard.
As of now, λ works in blogger whereas 𝛌 breaks blogger -- gets replaced by �.
Similar breakages are current in Java, Javascript, Emacs, Mysql, Idle and Windows, various fonts etc etc. [Only one of these is remotely connected with python]

So BMP is practical, 7.0 is idealistic. You are free too pick 😏😉
