I hope no one else implements this as it’s a security risk. This does not open you to XSS attacks only, people can use XSS to start different, more serious attacks or possibly execute a different attack altogether. Just all around not a good idea. I understand your use case and such but really not a good idea from security standpoint.
At some point in the future we hope to implement code blocks or something similar to say “Don’t sanitize/balance content inside this block of code”. This will alleviate most of these types of issues. This is not set in stone, just on our feature request list.
