What does this PR aim to accomplish?:

Wildcard DNS, for those who don’t know – is a trick to allow any kind of host name – to have a specific same IP as it’s DNS name. For example, if my domain is test.com and my IP is 1.2.3.4, the record full.test.com will also have the same IP: 1.2.3.4.

How does this PR accomplish the above?:

I wrote 3 new admin commands which do this.

Thank you for the submission, however unfortunately we are no longer accepting new features for version 5 of Pi-hole.

I could potentially see this being acceptable as an idea (not nessacerily this implementation) in v6 - but It should be discussed first with @DL6ER, he may have some opinions on why this is not currently a feature...

Closing for now, but thanks again for the submission!

This is already available via regex blocking which is a much more powerful tool when it comes to wildcard matching. You can easily reconstruct your example using something like

(^|\.)test\.com;reply=1.2.3.4

to get the behavior you are describing above. I don't think it's a wise idea to add "the same thing" twice in a different form as this makes it hard for users to decide when they should use one or the other.

You said this is already available, I agree. It is already exists in dnsmasq. PI-hole has used dnsmasq, I just add some commands in Pi-hole's script.
If this feature exists in dnsmasq, why it can't be used and your solution is not clear.

I really I don't understand this patch has some changes and you didn't get it.
