I'm not sure it is 'clearly' a symbol. To the compiler, there is no difference between int and your Int - they're just different names for the exact same thing. Depending on when the translation occurs, it may not be sensible to think of them as separate.
alias declarations should just accept built-in types. If someone for some obscure reason needs to exclude them, template constraints are good enough. There is no reason to make built-in types behave specially here.
Agreed. -- Simen
