We barely have 1.7 modpacks- how long ago was 1.7 released?
Thats the timescale we're dealing with- should it even be worth the effort and pain of breaking everything AGAIN for mediocre vanilla "features"
Regardless of what's actually said- Mojang's physical developments are very anti-modding at the moment; for a "released/finalised game" these code restructures have thrown everything back into a state of perpetual alpha- which makes maintaining a mod needlessly more resource intensive than it otherwise would be.
In the long term [
years at this rate] it may be worthwhile for modders- but for now we're better off sticking on the current MC version until theres a working API.
Access to a stable code base would free up a lot of dev time- allowing for more intecrate, complex mod behaviour, and make modding itself more accessible to new devs. We can continue building our own APIs, to service our needs without wreaking havoc with our current progress.
This is of course assuming Mojang's API will at some stage be a) actually working and b) practical to use- otherwise there's no point at all in using it. If theres no point in using it- theres no point in porting to that MC version.
At least if we stay on our current version then we'll be in a strong position to continue developing our own APIs without rebuilding everything.
If the official API ever becomes useable and viable- then everything breaks once, rather than every X months.
