Indeed, that works, thanks. I've installed erc-5.4.1.48598.0.20220420.474,
which seems to be the most recent version. Unfortunately, it isn't
obvious what has changed wrt vanilla erc, so I must use ediff-directories.

Well, this is also good. But for analysis it might be better to read the
files with the patches applied.

Oh no, please don't underestimate my lack of English!

I wouldn't call it fair game. With the Tramp examples you have seen,
that a :max property greater than 1 makes sense.

Yes, please do so. Hacking around bugs will always result in further
trouble mid-term. A bug must be fixed where it happens.

Btw, there are further dficiencies. For example, I believe the pass
backend does not support the :create and :remove properties (last time
I've checked, it were only netrc and secret backends which do). But this
is perhaps not the most important problem.

Could you provide the (changed) test files together with the erc
package? This makes it more simple to puzzle all changes together,
instead of accessing different web locations.
