I suspect a minor rephrase of this comment would be more than sufficient for me: "This field corresponds to the number of template arguments, which is expected to be at least 1024 according to [implimits]. However, as this limit is somewhat easy to hit with template metaprogramming we'd prefer to keep it as large as possible. At the moment it has been left as a non-bitfield since this type safely fits in 64 bits as an unsigned, so there is no reason to introduce the performance impact of a bitfield." I'd suspect you/someone will bikeshed that, but I think it gets the point across that I want to make sure is there.
