Hey Eric,
Do you know if we can do that with no consequences?
That depends. From Liferay, we tried to remove all of our usages on Lodash. Other than missing some usages (like that of forms), it should be safe from out of the box features. The consequence of disabling Lodash is that if you have code depending on it, it will fail to work, so wether it will have or not consequences is pretty much a very specific question that only you can answer.
why lodash is active by default?
As I stated before, disabling Lodash should be safe from a platform's point of view, because we no longer depend on it. Since we can't tell if you need it or not, we keep it enabled in 7.1 to make sure we don't break existing code and installations. We disable it by default in 7.2 because you can then make the choice of updating your code or enabling Lodash.
In summary, if you know you don't depend on Lodash, it should be safe for you to disable it. We can't make that decision by default on 7.1 because it would mean introducing a huge breaking change.
