If it hadn't been for the last sentence:

>At some point it would be easier to rewrite code from scratch with less complexity and overhead.

I'd agree, and probably wouldn't have commented.

But I think being all of these things:

>consistent, predictable, cheap, generic, and ubiquitous.

Means you have a damn good product. No one is claiming you can't get something better, but come on, I'd love to have software that's consistent, predictable, cheap, generic, and ubiquitous.

If those words describe a popular library, and you decide instead to build your own thing in-house... you better have a really REALLY good reason for doing it.
