> docked operation (TB4 dock)

maybe Linux but could also be specific to the Dock, many docks are not tested against standards but just Windows and/or Macs and sometimes just one of them, too.

I have a long history with them too, but I did ran into problems in more recent (T440, T480s) models. E.g. their USB-C charging ports are _very_ prone to breaking when there are frequent slight amounts of up/down force and there are only two and you need one working for charging to work. I have "bricked" one laptop this way and the only way to repair it is to go to a repair shop which can solder replacement ports on it... Not an issue I ran into with the framework the USB-C ports didn't break due to wear (yet) and even if they did they are trivial to replace (as you just replace the expansion card they are on).
