I just realised something obvious: the biggest advantage Joinmarket has over other coinjoins is, you can choose an amount and time, and that means you can feasibly make a payment as a coinjoin.
We have always known this advantage is very flawed because the recipient behaves distinctly in spending from other outputs.
But: if the recipient spends in a coinjoin structure (real or fake) it removes that trace.
I was just reminded of what an excellent, concise summary of solutions for (EC)DLP this blog is:
Currently reading and studying interesting Lightning RFC anchor output discussions in PR 688
and the last 2 lightning-dev meetings
which have a compelling intersection with Bitcoin Core package relay
and merged PR #15681 "[mempool] Allow one extra single-ancestor transaction per package"
... no agreement yet in sight :)
So apparently right now in #Spain, ISPs were ordered to block access to #GitHub. I haven't seen a news article myself, but it seems to have been targeted at #Catalan developers, but somehow many more random developers are affected, perhaps GitHub is even blocked nationwide. I don't live there anymore but my friends there tell me. This is insanity. The government accidentally ordering ISPs to block all access to GitHub. I'd not be able to do any work that day. Or week. We'll see.

Taproot review moving to week 4. There's a section on resource limits that I will actually try to read, since this is a difficult area I haven't had a chance to get on top of yet.
Yes it's good if people play around with different behaviours. I would recommend using CLI and trying "both sides of the market" so to speak, also Traca's idea about using basically zero fee to gain more participation is worthwhile (I still think though, that as things work today, the "royal road" is to mix Taker and Maker roles).
Should be new release pretty soon, we are working pretty hard right now, because so many rough edges need to be smoothed over ...
