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!
When I worked at agencies, it became clear to me that the audience for a company's website was not that company's customers or prospective partners or anything, it was that company's execs, who were often on IE two versions back from what was current. Thank goodness the earliest I ever had to support was 7.
