As a web developer, this approach seems very unnecessary to me. Are there
other properties that retain this sort of special handling? Wherein they are
meant as readonly but are mutable for compatibility reasons?

I fear this attempt to prevent confusion will actually create more.

This information within `performance` is very much tied to the user agent;
augmenting the navigator object with it seems very natural.
