There are other ways too. HTML / JavaScript doesn't prevent this.

If you're really paranoid about such things, you can investigate NoScript or something similar.

Plus, in general, as long as disliked.service.example.net and webapp.service.example.com are on the general Internet, they can communicate directly server to server.

This is just a core part of how the Internet / Web were designed. We can't prevent that.

The speedbump we're proposing should mostly alleviate your concern as far as Intents are concerned. Yes disliked.service.example.net may be opened, but the UA won't deliver your data to that service until you confirm for the first time.

Note that UAs can certainly adapt to providing a Ban list for certain Intent Providers. So if you want to tell your UA that disliked.service.example.net should never be used, I'd expect we'll see that. We could probably put in text encouraging UAs to support a user controlled blacklist for intent providers, that isn't unreasonable, although it's merely a SHOULD as it wouldn't have any implications to the API itself.
