In my opinion:
The real issue isn't whether TE or SOD is better. Let's assume TE is better than SOD (which is probably true). The question is about a well-thought-out strategy for successfully implementing the better option when there's already something acceptable. Here, the way it's presented and marketed becomes crucial. (I've already given the example of IE and Netscape; you could also add 1C, where competent management and marketing played a decisive role in its success). From this perspective, the availability of a "SOD-version" of TE, along with ease and simplicity for initial familiarization and use, becomes critical for successful implementation. Forcing all options into a package, following the principle of "buy everything at once or nothing," is counterproductive and doesn't contribute to accelerating the implementation process.
End of my opinion.
P.S. I'm a fan of this great game and sincerely want it to improve and for players to have a more convenient and interesting experience!
