    those are technical arguments - i'm not sure how you can understand them
    to be "personal preferences". The only personal preference i have is
    that in the end a technically most superior solution should be merged.
    (be that one project or the other, or a hybrid of the two) The analysis
    of which one is a better solution depends on pros and cons - exactly
    like the ones listed above. If they are solvable problems then please
    let me know how you would solve them and when you (or others) would
    solve them, preferably before merging the code. Right now they are
    pretty heavy cons as far as LTT goes, so obviously they have a primary
    impact on the topic at hand (whic is whether to merge LTT or not).
