Support of OptiFine_1.7.10_HD_U_E7 (old MC version but with powerfull modpacks)

[Ngar1]

Vivecraft supports only the very old Optifine version "D1" which is since longer time incompatibe with serveral mods. Ideal would be the support of OptiFine_1.7.10_HD_U_E7, or as minimum OptiFine_1.7.10_HD_U_D6.

I play GregTechNewHorizons Modpack with very active modding community, but they cant help to support such old Optifine version. This modpack is supported since 7 years, with many new release and new (& exclusive) mods per year. 1.7.10 is "old", but with newest mods newer MC version is not beats it.

Is there something to motivate this update?

1.7.10 is discontinued. There are no updates.

Yes, I know and had been written. The question is, what would motivate to do it?
