No, there's really no space for wriggling here. You use getrandom() or, in the worst case, /dev/urandom, and this kernel nit goes away. It was never the case that the LRNG was "exhaustible"; there was only a broken interface to it.
Personally, I forgot that Linux only fixed /dev/random in 2020 in kernel 5.6. That's not that long ago in terms of enterprise / LTS kernels. I'm sure this has been a surprising pain point for end-users for a long time, and perhaps still is in some environments.
Right. But the context here is whether languages can make the (very big) decision to default to a CSPRNG, in which case: you make that decision once, for all your users, and when you do, you don't use "/dev/random".
