@andros I give you not creating another file, but then I'd vote for commenting out DMs. See https://eapl.me/timeline/post/z5e2bna

It's easier to find the DM in comments from your side, than asking all the client maintainers to add the regex =P You can even use a Modified comment, such as #! <DM content> Or something like that

This approach is retro-compatible with current and older clients.
