The comparison is indeed pretty thin; it certainly doesn't come anywhere near the miscommunication and whiffs of NIH that are present in the Dep case.

It still made me think of it, because in that thread there is a domain expert which lays out careful reasoning for the decision to place constant-time arithmetic inside big/int. Among some other discussion, the main hangup is about the placement of the code, and not any core maintainer is signalling go-ahead with any direction. The issuer author could of course continue to work out the existing strawman proposal, but that risks to be abandoned if the core maintainers turn out to change their mind.

Meanwhile, on March 19 2018 a core maintainer asks if "anybody want to fill out this proposal to see what changes would be required in math/big?", despite that the issue itself has an extensive PR with test suite which reveal most of the necessary changes. (either that or it refers to the Aug 17 2017 comment, but that seems to be exactly bford's proposal with a different public API)
