The reason for that was to immediately make contracted braille available to all 
users without searching for a new binding in each driver. If we go to just 
using contraction tables then that toggle can go back to really being for 
six-dot braille.

In a way, though, that'd be less user friendly as scrolling througha long list 
of tables is much harder than pressing a key combination.

The idea would be to have tables which implement the one-to-one mappings plus 
others which include those and add contractions.
