Julia does not reject incompatible package

[GHTaarn]

I created a simple package and in the compat section of Project.toml I restricted the compatibility with julia = "1.0 - 1.7". I then tried to add this package to a newly activated temp environment from Julia 1.9.3, but this did not produce an error or warning. The following is a snapshot of the REPL:

My understanding is that an error should have resulted. I made a post about this on discourse at https://discourse.julialang.org/t/package-compatibility-constraints/103217 and none of the responses convinced me that this is the intended behaviour of Julia.

The entire source code of the package is available at https://github.com/GHTaarn/VerExperiment.jl

I am using Ubuntu 22.04 on x86_64 with Julia installed with juliaup.
