Ohh, conditional comments. We had so many IE holdouts on our site, I think only around 2021 I removed the last IE specific fallbacks, and I think some conditional comments were a thing until 2020.

I’m not sure when I removed a bunch of `msapplication-` fields, but probably after 2021 ;)

I guess I can remove `apple-touch-` and `application-name` stuff next…

Conditional comments are still part of HTML email templates. Though soon will be dead I hope. Thanks "classic" Outlook!
