With respect to your first sentence, all I can say is, of course; is there
anyone who thinks differently?
In a signal generator, where source match is important, there will probably be
an attenuator, or at UHF and above an isolator (terminated circulator), that
dissipates returned power. Otherwise, almost all amplifiers are mismatched to
returned power and simply reflect it, as does any mismatched load.

You have to remember that the built in tuner matches the amp to the
transmission line. It does nothing to improve the SWR at the antenna or to
protect your coax.
Well, it might incrementally improve the loss in the coax because the reflected
wave from a high SWR antenna would not be the-reflected at the amp. It would
be fully absorbed into the amp which is well matched.
The really good thing that the internal tuner does is make life easier for the
amp. You will get more power out because the protection circuits don't have to
protect the amp. I'd be far more protective of my amp than my coax!
