Hi Tobias,

I agree that the situation is far from optimal, but this is the wrong package
to report this issue to.

Rather, packages that depend on nlohmann-json3-dev should try when possible
(that is without breaking shared libraries ABI) try to migrate to the new
upstream version nlohmann-json3.12-dev which fix a number of bugs.

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1060164
for why we needed a new package name.

Cheers,
Bill.
