This is not theoretical; it happens quite frequently. For toolchains, in particular I'm aware of how Apple (not that they're unique in this) has "blah blah open source" downloads, but often they do not actually correspond with the binaries. And not just "not fully reproducible but close" but "entirely new and incompatible features".
The ARM64 saga is a notable example, which went on for at least six months (at least Sept 2013 to March 2014). XCode 5 shipped with a closed-source compiler only for all that time.
What does that mean for a linker? If you ship a binary linked with an AGPL linker you need to offer the source of the linker? Or of the program being linked?
AGPL is avoided like the plague by big corps: same big corps are known for having money to pay for licenses and sometimes (yes, I look at you Amazon) being good at deriving value from FLOSS without giving back.
iirc AGPL was used so everyone can just use it, big biz is still compelled to buy a license. this has been done before and can be seen as one of the strategies to make money off FLOSS.
