Seems a bit of overkill so I voted no. I also agree with insiteFX, and would add that many more users want an auth system or template library which everyone would use, but that is ruled out as easy to self implement. Surely the same can be said for this unusual and (IMHO) 99.9% of the time unrequired addition.
As JayAdra said, if it is just a helper you need not use it, but then again, that could be said for lots of things too, like a multi-file upload helper, or an Ajax helper, or an oauth helper.
Laraval 5 is using this - a coincidence? Or have I undervalued this unique tool?
PHP league have TONS of great stuff. How about a helper for omnipay? Or Glide? But all of them can be implemented anyway, relatively easily, so do these really need to be helpers?
I am going round in circles back to no. So I voted no. Sorry to be negative.
Perhaps a better definition, philosophy or reasoning behind the helpers needs to be defined. So Fly System could be measured against these helper objectives. "Helpers, as the name suggests, help you with tasks." is very broad.
