Hosting content isn't free. It makes good sense for Homebrew to only host pre-built bottles for the configurations that the vast majority of MacOS users are using (and should be, if the machine is ever attached to the public internet). If you are the kind of user who doesn't fall into this category, it's a feature not a bug that you can still build the catalog from source on your own dime.
