Hi, I noticed Discourse HTML code having below kind of lines <link rel='preload' href='/assets/browser-update-xyz24ff41586d6dcda055f0cfb41488724ba2e2d5271fef65ce5f480b46f9231d.js' as='script'/> <script src='/assets/browser-update-xyz4ff41586d6dcda055f0cfb41488724ba2e2d5271fef65ce5f480b46f9231d…

AFAIK IE is still supported until June, although support is currently being moved into a plug-in.

Most of my audience are familier about latest browser. I would be happy to ignore support for IE.

Move Internet Explorer support to core plugin Discourse will be dropping support for Internet Explorer in June 2020. (A formal announcement will be made mid-January). In preparation for this, Internet Explorer specific code has been moved into a plugin, making it easier to remove come June. Source

Why would preloading be a problem? I do not understand your request.

There’s no such thing as IE 18.

It has been ok for the past ~six years. Six months more isn’t a big deal. The reason to spin out IE support is more to reduce complexity than any burden created from preloading.

I hope, in next 6 months it will be removed.
