Limitations

You couldn’t & you can’t revert from the current stable firmware to the previous stable firmware version
Example:
Reverting from v7.3.0 to 7.2.0 →
Reverting from v7.3.0-RC.22 to v7.2.0 →

Prerequisites:

1. a backup!

2. the Recovery mode & adv. options guide by @Dijker might come in handy.

How to:

What is key: You have to disable “Experimental updates” prior to your backup creation…
When you restore THAT backup again, it keeps your Homey at stable firmware version after factory reset.
Otherwise it will just update to RC firmware again, non-interuptable.

disable “Experimental updates” @ Homey Developer Tools

open the mobile app

hit […More] > [Backup] and create a backup

when it’s finished, turn Homey upsidedown OR, open Homey Developer Tools and press [Restart into Recovery];
wait for about 30 to 60 seconds

@ mobile app, hit […More] and press your Homey name below your account name (at the top)

press [New Homey]

select [New Homey Pro]

connect to Homey-xxxxx SSID and when asked, select your wifi SSID to connect to

“A Backup is available, install it”? → press NO

press [Options]

pick [Factory reset]

wait for it to finish

in app screen, hit [New Homey] again

connect to Homey-xxxxx SSID and when asked, select your wifi SSID to connect to

“A Backup is available, install it”? → press YES

now Homey restores your selected backup and installs unidentified software updates

wait until Homey has completely restarted

wait longer

again, press [New Homey]

select [New Homey Pro]

(… my wifi-setup now couldn’t find Homey-xxxxx…)

abort wifi setup by hitting [X] at the top-right

when all went well, your “old” Homey suddenly has been added and is selectable now.

.
Findings:

The deprecated tado° v3.x app was still present after factory reset and backup restore… while it’s not in the official app store.
As far as I knew, a restore downloads your apps from the store. It probably saves apps which aren’t in the store anylonger.

the backup actually works
