Stability is good is what's stable meets your needs.

The more they stall adding stuff like generics the more painful (and more work for the tools and ecosystem to catch up) will be when they eventually cave in and do it...

And there will always be all the workarounds, third party solutions, and wasted efforts that would could have been avoided if something that could have been delivered early on (like e.g. package management) didn't come a decade late for no good reason.

At least now they've come up with a module/dependency system, which, even though a decade late, doesn't bring anything extraordinary to the table compared to what other platforms already had for ages.

Generics and error management remain before it makes sense to make it stable and boring for eternity...
