I would prefer to see 2 options in browsers:

1. LSAT[1] support for micropayments (recently mentioned on HN[2])

2. RandomX[3], mining XMR for the site owner

Both provide something useful, replacing advertising and/or subscriptions for the site owner, rather than solely wasting energy. Let's eliminate captchas and advertising together.

  a memory-bound graph-theoretic proof-of-work system (by tromp)

The use of scrypt as underlying hash function is a rather poor choice though, as scrypt's memory hardness makes PoW verification unnecessarily expensive.

It's perfectly possible to make a memory hard PoW that's instantly verifiable, by using something other than hashcash. Examples include Cuckoo Cycle [1], and Equihash [2].
