I have voted it there but it is more about replacing xt9 with presage which I do not see feasible solution in short term. Presage may require more own work than using xt9 requires and thus for commercial use and product creation with limited resources xt9 might be still better option. However xt9 won't be ever open and this might be also matter of resources.

Current xt9 as it has been implemented is also pretty useless. I am used to prediction system in iOS that allows me to write blindly as it replaces the written alphabets with proposed ones automatically. I can write words where no character is correct and still the prediction system finds the correct one automatically. Not always, but for most of the words. This xt9 system as it has been implemented in Jolla shows list of words where you need to select. With the time and effore to read the proposed words and select from those I can write the whole word and thus this current solution is useless for me.
