i second this argument

ideally, all extensions should be explicit use cases, not generic/implicit layers that can be exploited for unknown and possibly harmful use cases

also timing is critical for all bitcoin innovation.   look at how lightning ate up fees

to keep bitcoin stable, we can't "scale" too quickly either

i'm a fan of, eventually (timing is critical), a lightning-compatible mimblewible+dandelion on-chain soft fork can reduce tx size, move us from l2 to l3, vastly improve privacy, and get more small transactions off-chain.

but it probably shouldn't be released for another 2 years

Again, what I said was "compelling use-cases _clearly_ beneficial to _all_
users", not just a small subset. I neither think the use-cases in those links
are clearly compelling in the current form, and they of course, don't benefit
all users. Indeed, the Drivechains use-case arguably *harms* all users, as
Drivechains is arguably harmful to the security of Bitcoin as a whole.
Similarly, the various new uses for on-chain transactions mentioned as a
use-case arguably harms all existing users by competing for scarce blockchain
space - note how ETH has quite high on chain fees for basic transactions,
because there are so many use-cases where the per-tx value can afford much
higher fees. That kind of expansion of use-case also arguably harms Bitcoin as
a whole by providing more fuel for a future contentious blocksize debate.

Bitcoin is an almost $1 trillion dollar system. We have to very carefully weigh
the benefits of making core consensus changes to that system against the risks.
Both for each proposal in isolation, as well as the precedent making that
change sets.
