For codebases such as Vulkan, the types and functions follow a defined structure. However, when generating C#, due to the current behavior of --with-attribute, I must manually list all enums that should have the Flags attribute in the .rsp file. If --with-attribute supported regex, or if a new --with-attribute-regex option were introduced, this could reduce dozens of lines in the .rsp file to a single regular expression. The latter approach would also be opt-in, meaning existing .rsp files would remain unaffected in terms of both performance and functionality.
