Josh Elser commented on SLIDER-337:
-----------------------------------
[~hsy541], I think I'd agree with you. This was very much a work around to make
sure that we don't flat-out fail. I'm not familiar enough with how the library
providers are used, but you should feel free to open another issue to make them
configurable. We can have discussion there :)
