Hi Joseph

That's a good news that you take my suggestion in consideration. Many
thanks!

I admit that Tony's add-on was not the best example since in some way, it is
blocked for personal reasons and by the lack of an alternative maintainer.
But there may be some time between a valid PR against addonFile and the
website update. E.g. currently Focus Highlight update asked a week ago.
As you stated, it is due to the website update process and this may not
change until the store is up and running.

You seem to plan to implement the mechanism only for stable channels. I
would recommend instead to implement it for both stable and dev channel.
Here is a user story explaining why:

User story 3:
I am a user of TheWonderfulAddon version 2021.1 that I use daily for my job.
Since this add-on is important for me, I want to test each new version to
check that it still fit my needs. Thus, I subscribe to dev channel for this
add-on.
A new version (2022.1-dev-1) is proposed by the add-on updater and I install
it. I use this dev version in my daily job to check that I can still use it
for the tasks I have to do.
After some time, I realize that this dev version contains a regression that
prevent me from doing my job correctly. Thus I uninstall 2022.1-dev-1 and
reinstall 2021.2. I also report the issue to the add-on author.
I would like add-on updater not to bother me anymore with 2022.1-dev-1. But
I also would like add-on updater to inform me when 2022.1-dev-2 is available
so that I can test if the issue I have reported has been fixed.

Hope my request is clear.

Cheers,

Cyrille
