We can re-use some other tool as well, no need to code our own in Guile
though. Also note that the choice of bug-tracking tool is not benign,
as most other tools (Mumi, but also QA) have to adapt to its
idiosyncrasies.

I don't agree: see below for the two examples of where the tool design
itself is problematic.

I prefer a public-inbox web frontend for browsing emails personally.

I don't think there's a "public" discussion of this, but I've conversed
with the mailman maintainers in private about this: because Debbugs
relies on modifying the mail message itself, it clashes with modern
email features that authentify received emails.
DKIM authentifies a subset of mail headers by signing them with a
private key, among which the "From" header is mandatory. DMARC is a
policy mechanism for domains that can enforce DKIM (and/or SPF) for all
mails with a corresponding "From:". Together, they prevent email
impersonation.
So Debbugs modifies a protected header (e.g. Subject) -> DKIM fails ->
if DMARC is set to enforce DKIM, DMARC fails -> mail is not received.
To avoid this issue, Mailman (the mailing daemon overseeing the
debbugs-managed MLs) also rewrites the From: header of such mails to a
debbugs-controlled domain, so that DKIM headers can be re-signed and a
different DMARC policy be used. This is why you often see "via
guix-patches" in From: headers, and if you look at the email it's a
generic one.
I've also mentioned this before, but not being able to simply send a
full patchset without having to go through hoops is, put simply, a
problem. Even prospective contributors used to email-based workflows
will be turned off by this.
In general, the problem with Debbugs is that it insists on *taking over*
emails, rather than just consuming them.

Yes, I was mentioning general tools.

I like this separation as well, and Tissue seemed interesting the last
time I looked at it. I liked how it uses standard tools and can be
consulted/modified off-line. It basically checks all of the boxes :)
Best,
