What if we tried a completely different type of solution (which might solve the issue for protocol default conformances too)?
Right now there are errors and warnings. What if we add a third type of compiler feedback (let’s call it a note). A note is a little bit like a warning, but it can be dismissed/acknowledged. It is only generated once for a particular issue, and then it is remembered that you dismissed it so it won’t come back every time you compile. So in this case, when you add an Equatable conformance post-hoc, you get a note (let’s say it looks like a warning, but is grey instead of yellow and has a different icon) saying something like “Equatable conformance was automatically synthesized”. If you want to remember to add your own conformance, you can just leave the note there as a reminder to yourself until you do it. If you want the automatic conformance then you just dismiss the note and it never bothers you again.
