A compiler is frequently described as mature if you don't need any other language compiler to compile it - e.g. C is a mature language; you can use a compiler written in C to compile other programs written in C.
Is there a term for - not just the -opposite-, but a way to describe when you want to -preclude- a tool from being used as part of its own toolchain?
Currently chewing on the notional word "abnitial" (ty @djm for the inspiration) as a base neologism to with for this concept
@robryk
Yes. Without -any- dependency on the product.
In another branch we've come up with 'abnitial' as a word to use to describe this concept.
