This disclosure is great to see, got an email and immediately patched my apps annd redeployed with no downtime and minimal exposure. Meteor is an amazing time saver and a superb framework/build process.
I used to be strongly in favor of Meteor as a time-saver but as I got more exposure, I realized how weak and annoying it is to work with.
You are largely stuck into Meteor's ecosystem and at their whim, meaning you have to do things "the meteor way". Things like methods and promises ("Futures") are annoying to me because they abstract away so much.
Maybe it is just a matter of "growing up", but I think I am going towards more non-framework frameworks like Choo.js in the future. I used to think Meteor was a quick prototyper, but Choo is infinitely quicker.
You don't need to use methods if you don't want to. It's pretty easy to integrate either rest via an integrated express server or if you prefer GraphQL you can host your GraphQL in Meteor.
As for Futures, that's not necessary as you can now use ES7 await in Meteor seamlessly on both the client and server out of the box.
