support disabling subdomain propagation for specific domains

[Rudxain]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

Some domains have homepages without subdomain (such as www.*), which causes dyna-rules to inappropriately apply subdomain-propagation.

What if a user wants to

no-scripting: * true
no-scripting: discord.com false

without having to add

no-scripting: support.discord.com true

?

What about

* * 3p-script block
github.com * 3p-script noop

without needing

docs.github.com * 3p-script block

?

A specific URL where the issue occurs.

https://discord.com/

Duplicate of #1277.

How so? I'm sorry for the misunderstanding.

I didn't mean "add/remove sub-domain prefix", I meant "change the behavior of the rules themselves (opt-in)".

www.discord.com redirects to discord.com (same for GH), so any rules that apply to the homepage also apply to sub-domains. I want to "focus" on home only, without affecting subs

In that case, a duplicate of :

• Dynamic filtering: add option for strict partyness #2912

user31415192 : I want it so that uBO has an option for a dynamic filter to not propagate to subdomains.
