Verkle trees only reduce proof sizes by a factor of 6-8, and they introduce
significant implementation complexity and new cryptographic assumptions. Better
to let other crypto-systems get a few more years of experience with them before
adding them to Bitcoin. Particularly since even having merkle trees in Bitcoin
is arguably a mistake: they allow for degenerate, weak, security modes like SPV
that aren't clearly good for Bitcoin as a whole.
