But it is an uninitialized optional

A semantically sound implementation of the comparison operators was removed from Swift 3 in SE-0121. See that discussion for detailed rationale.

That discussion happened > 7 years ago, many things changes since then. Now we have mature generics and it it would be possible making a conditional conformance to Comparable. From the pitch:

However, this doesn't work in current versions of Swift, because generics don't support conditional conformances like extension Optional: Comparable where Wrapped: Comparable, so Optional is not actually Comparable.
...
Until generics are more mature, the issue of Optional being conditionally Comparable can't be fully discussed/implemented, so it makes the most sense to remove these questionably-useful operators for now (a breaking change for Swift 3), and add them back in the future if desired.

Good time to have this discussion or everyone is happy with the current status quo?
