Jeffrey, If I may....
- Method (with code customization) - physically will remove links from the code.
- Methid (with Custom CSS) - will hide links from the users eyes, they won't be able to click them in normal way, but they will be still in sourcecode.
I don't think so that Joomla 4.4 allows to hide those two links by default, that's why it request extra efford from webmaster.
If we talk about Login component view below Custom CSS (#2) will hide all 3 links below Login Box:
.login .list-group > a {display: none; visibility: hidden;}
