I uploaded a new lmtx ... kind of experimental because I changes some of 
the background bist that deals with embedding. The problem is that we 
need to deal with the previously reported clash between different 
unicode entries that share shapes (normally no issue but in this case it 
was a side effect of 'effective' monospaces where the font decided that 
invisible shapes should he visual anyway) as well as with the fact that 
soem cjk fonts have many duplicates which makes us cross the 65 boundary.

The variant approach is ok but I might have overlooked some soecial 
cases. Because this also drops 'stream compatibility' between mkiv and 
lmtx (which had already become somewhat loose) I can now also clean up 
(simplify) some other parts of the font system but let's do that 
stepwise (I'm in no hurry here).
