Update: Tails 3.14 should ship Electrum 3.2.3-1 from sid. That won't
help it connect to the network but at least we upgrade to the newest
version that's in Debian, which is the best we can do.

So I understand that basically, as of today, we would trade "Electrum
in Tails can't connect to the network most of the time because we run
a deprecated client version" (the current situation) for "Electrum can
use the configured trusted Onion server only when it's not DoS'ed".
I guess this would be a usability improvement but it does not seem
sufficient to make Electrum in Tails really usable.

The risk×impact does not seem too bad to me. At least, not enough
to be a blocker in itself.
So all in all, my current take on option A is: at least as long as the
DoS issue is that severe, this option doesn't seem to provide enough
usability benefits to be worth doing the work and taking the security
hit. And we're thus left with option B:

Any progress on this front? Could you please point me to the
corresponding mailing list thread?
(And if you only did private email so far, I suggest you switch to
using that team's public mailing list in the future, which fits the
Debian culture better and has thus more chances to work :)
Please Cc me further communication with the Debian Cryptocoin team, if
you don't mind. It'll help me assess whether, and how much, we as
Tails need to invest into co-maintaining the package.
