"Viable" as in "you have no other choice sometimes". This forces you to deal with 3 libraries each with their own quirks, pitfalls and incompatibilities. Sometimes you even deal with dependencies reimplementing some parts in a 4th or 5th library to deal with shortcomings.

I really don't care that much which of them survive, I just want to rely on less of them
