I would say that "cannot be read back" is a bit harsh. After all, I
could write:
nd thn thr wr wrds
which is lossy due to loss of vowels, and while it could be read as
"Aenid thine thor wore wards"
it is obvious it is meant to be: "and then there were words"
There can be lossy encryption that is still readable. It is a matter
of being logical. If someone claimed that the above encrypted
sentence read "now therein three wicked witches read spells" I would be
sceptical of the outcome. There is just too much "there" not
there.
That is what shorthand is all about. Giving enouch of the word
context without needing to write it all out.

(I'll post a table when I finish it). It is interesting that many symbols mean different things in different contexts (e.g. the glyph as a suffix vs. prefix; even in different words, they mean similar things but not exactly). So, if the same glyphs were used for multiple abbreviations, the result becomes a lossy compressed text that cannot be retrieved back accurately (unless you know exactly what you wrote). As a consequence I bet that the increase of entropy that should be due to the abbreviation, would be lost by the multiple mappings of the text into the same glyph. Short words, text very redundant and therefore low entropy... but unfortunately this could not be read back.
