network site alias domains

Sometimes I like being able to refer to a site using either https://www.dom.ain or https://dom.ain .

While I *can* go in to my apache configs and say:

RewriteCond %{HTTP_HOST} ^.*\.dom.ain [NC]
RewriteRule ^/?(.*) https://dom.ain/$1 [L,R,NE]

that’s extra work I have to remember to do when I create a site, and extra work if I remove a site.

Similarly, if somebody wants to have multiple domains that map to the same site, I can go into my apache configs and say:

# Yes, the following is a bit sloppy…
RewriteCond %{HTTP_HOST} ^.*\.dom1.org [NC,OR]
RewriteCond %{HTTP_HOST} ^.*dom2.com [NC,OR]
RewriteCond %{HTTP_HOST} ^.*dom3.org [NC]
RewriteRule ^/?(.*) https://dom1.org/$1 [L,R,NE]

but I still have all of the issues noted above.

Would it be difficult to have the ability to list “domain aliases” when creating a networked site that would handle all of this for me?

Yes, this is more of an issue for me because I like to use “domain” network sites instead of “subdomain” sites, but even then, I think this would be a useful enhancement.
