Regardless, I'm happy how it is but I can understand if some are confused as the term pushback left or right is naturally ambiguous.
Which is why, the GSX manual as a diagram explain what Pushback Left/Right means, which can't be misunderstood in any way.
And, as already noted, GSX uses the same convention as default FSX. Since GSX reads the AFCAD for the pushback preference and that is obviously based on the FSX standard (and GSX is the same), reversing it would be VERY confusing, both for users and for scenery developers.
Imagine opening a scenery AFCAD with ADE/AFX and reading a "Left" pushback: if GSX worked in the opposite way, you would need to force yourself thinking "ok, the AFCAD says Left, but this means Right in GSX, or maybe not, depending how I've set my preference".
Sorry, no, this doesn't make any sense, and we also don't have any intention of having to always ask people that report a problem with Pushback "what's your setting for Left/Right", it will be a support nightmare.
So no, the GSX Pushback will remain as it is now, respecting the FSX standard convention.
