People have a hard time orienting if coming from js, where a 'stable' project means refactoring the entire code base to keep up with the dependencies refactoring their apis every 2 months.

plus, they are investigating old edgy errors in many issues, rescuing them (already closed) from the old project.

A fairly unidiomatic rendering of "lively", I think.

Definition 3: “Full of life, strikingly alive.”

Etymology: “Borrowed from Latin vividus (“animated, spirited”), from vivere (“to live”), akin to vita (“life”), Ancient Greek βίος (bíos, “life”).”

I like it!
