I think the idea is great, but I was wondering if it could be =! instead of !=. IMO, I think of != could be a bit confusing. About the strong name, could it be override instead? Would it not be clearer?

The specific syntax is a proposal, but I'd say that the implementation is easier if it is in the option name. Also, in theory, options values can be anything, while options names cannot contain "!" at their definition, which makes a bit more unlikely that someone with an option finishing in ! will make it fail.

Regarding override, I am not sure, it will be ovelapping with the requirements overrides, which is a different concepts. Strong options can also override strong options, and regular options can override regular options... We can look for another name, I agree, but override I am not sure.

We can look for another name, I agree, but override I am not sure.

Just by simliarity with CSS's !important (Both have an !), we can call them important options 🤔

I like the idea of calling them important options and using the !
