@boxy When competing standards fail in the face of preferable competitors, they also become deprecated.

So it's not like it's a permanent state of things.

New standards can be needed, older standards can be deprecated. And then they can be brought back into recommendation when major flaws in the new standards that weren't noticed due to flaws in the evaluation process are noticed.

Or something new incorporating the better parts of both (and a bunch of compatibility stuff) can be made.
