The last time custom attributes where discussed, a C# like model was

C# uses a runtime implementation, not a compile time one.
Speaking of the distinction, it would be great if we arranged things
such that attributes are a lowering to existing D (i.e. the compiler
rewrites a nice attribute syntax into clunky D code you wouldn't want to
write by hand).
Lowerings have worked miracles for us in terms of keeping language
semantics simple and reducing implementation bugs. We should use them
wherever appropriate.
I don't think that applies here. We have no low-level mechanism to affect
the compiler internals, which is where attribute metadata belongs.
