Should PW set the X-Content-Type-Options header?

[Robin S]

A client hired a security consultant to do a site analysis and they advised that the X-Content-Type-Options HTTP header should be set to "nosniff".

The MDN docs for this header say: "Site security testers usually expect this header to be set."
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Content-Type-Options

This was easily resolved by adding the following to .htaccess

Header set X-Content-Type-Options "nosniff"

Do you think it would be good to add this to the default PW .htaccess file?

This is included with the default .htaccess file, but disabled by default. See section "4. Protect from XSS with Apache headers".

It seems to me that this should probably be enabled by default, but I'm guessing that it was left disabled for a reason – @ryan would be the best person to say if those reasons still apply.
