Sorry, but S4 is already added in another way, which accepts just an
S4 compatible string.
But for T7 we need a fallback.
Could you let me know what you're asking here? Redo S4 and add T7? Or
do T7 in another different way that I didn't get?
Do you want a v6 patch series? If yes, could you be more clear about
how you want it?
