I don't think there is any consensus that we actually want to increase the block size any further for now - that is the main reason why extension blocks have not been deployed. The hard problem is not how to do it technically, but whether we need to do it or whether we should stick to what we have now with Segwit and scale on layer 2 instead.
While the block-size increase was one of the effects of Segwit, it was not the only and perhaps not the most important one. Segwit also solves transaction malleability in an elegant way, which makes the implementation of layer-2 techniques (including Lightning) easier.

Take a look at the previous work on "extension blocks": https://old.reddit.com/r/Bitcoin/comments/63b8lb/purse_extension_blocks_ready_for_liftoff/dft4nj1/?context=1
Indeed, several people have pointed out to me that this idea has already been out there for some time, only it's been called "extension blocks", albeit not defined with as much detail. Started to read the discussions on it, seems very similar. Gonna continue reading to give them proper credit, but also to figure out why this proposal hasn't been greenlighted and what arguments could be used to showcase the benefit of its activation. I see it started in pre-SegWit era, maybe this time will be different because we have seen a successful SegWit activation, which is highly similar to the proposal in question, in the way SegWit was deployed.

Superspace: Scaling Bitcoin Beyond SegWit

Abstract. SegWit, or Segregated Witness, a soft fork successfully activated mid-2017 on Bitcoin blockchain, provided among other benefits a backward-compatible increase to the block size limit, all while not introducing consensus breaking changes to Bitcoin protocol and not resulting in a hard fork network partitioning. The potential space increase is estimated at being close to 2 MB total for practical purposes. In this paper, the author argues that it is possible, using the same mechanism, increase the block size further up to any agreed-upon limit, while still providing the same security guarantees SegWit does.

Keep in mind, it's only the first draft. I would really appreciate your feedback.
