Best practice to set limits for Julia version

[GHTaarn]

I tested this in a similar situation yesterday and it had no effect

Package compatibility constraints

I put the following line into a Project.toml for a package and am trying to figure out what consequences it has: [compat] julia = "1.0 - 1.7" When I try to add this package in another package from Julia 1.9.3 it is accepted without a warning and I can use it without warnings or incorrect behaviour. What consequences should I expect with compatibility specifications in a package?
