I'm not asking for the service to "exist". I'm asking Google to take twenty minutes and fix their solution, which already works but is security through obscurity.
Google seems to have built their brand intentionally to be the opposite of what you're asking for though; and absolutely they could be blacklisted with a simple "GMAIL ADDRESSES NO LONGER ACCEPTED HERE".

I'm not sure which one you are saying is security through obscurity here... [email protected]... or the high entropy [email protected], both are obscure, but its a stretch of imagination to start labelling this a security issue.

I think "you can't block GMail" here is meant in the sense that "you can't block the Google crawler". It's certainly technically trivial to do so, but the opportunity cost from lost users will be, for most businesses, unacceptably high.
Excellent interpretation. Gmail = Google crawler. I've made a note of this now.
What needs to happen next is a deep discussion between yourself and logicallee, in the context of Google crawler as well as how to make gmail come further out of the dark ages with high entropy and no security obscurity.
mkKAjgsdf788hf87hf is not the only possible high-entropy format, it could be if the type that gfycat uses such as "uncommongrimyladybug". That is quite hard to blacklist.
Nobody is ever going to stop accepting gmail addresses, that suggestion is pretty ridiculous. Especially since I suggest that these addresses should be delivered straight to your real inbox (unless they start getting spammed). There's no reason people should stop accepting them.
This a reasonably priced paid service that does already exist, it's not from Google and no, I won't name it neither publicly nor privately because I used it for years and I don't want their domain to be banned by those requiring your email address for everything. If you know how to search you will probably find it. Basically you sign with them using one valid email address, then on their interface you can create as many addresses as you need (IIRC there is a limit but I used even dozens at a time without problems) and add a keyword to them. All of those addresses will be redirected to the email you signed with, but the From: field will also contain the keyword you specified so that if you create an address for each service you sign up for, you instantly recognize who is spamming you when they use that address. This is very effective and I filtered out a lot of spammers. I'm surprised there are no more services like this one around, or probably there are many but they keep a low profile to avoid being banned. That's why I'm not going to name that service, sorry. But it does exist indeed and is technically easy to implement.
