and that is why the feature as written makes no sense to me… of course they need to be recognized, why else do they get the treatment and everyone else does not
And again, there is
nothing in the feature that says they have to be recognized. There is
nothing in the feature that suggests that your heroics are important in how people treat you. All the feature says is that you know how to fit in among commoners. There is absolutely no special treatment here and the only implication is that commoners are willing to help each other out, but are less willing to help people of other social groups out. Which totally makes sense in a typical D&D setting--or in the real world, for that matter.
You were a hero in your own town, and having had a taste of heroics, decided to go out and adventure. That makes a bit more sense than having a "Former Peasant" background and that says "you used to be a dirt farmer until one day you said '$@&! it!', threw down your shovel, and decided to go out and adventure."
And they are
not getting special treatment, no more than acolytes get special treatment because they can get healed for free, or guild merchants get special treatments because their guilds will give them legal representation, or hermits get special treatments because sometimes the cosmos tells them things. Every single background gets a feature. The folk hero's is even less useful than many because you don't even get treated to a lifestyle--just a place where you can rest and recuperate and have your hosts tell the guards they saw you going
that way when you actually went
this way, the latter of which isn't even going to be applicable 99% of the time, unless your PCs are on the run from the law a lot.
you know who else fits in really well with commoners? Other commoners, so most people (hence the term…), yet they do not get this treatment, only the Folk Hero does…
That's absolutely true. The vast majority of NPCs are commoners, and they're able to rest at each other's house and help each other out when the law comes after them.
The PCs, however, are probably not playing former commoners. In the actual example that started this pointless tangent, we had one sage (which overwrote any commoner traits they may have had, if any--maybe their parents were middle-class), one sailor (which overwrote any commoner traits they may have had, if any--maybe they were born on a ship), and one noble (who very much
never had any commoner traits to begin with).
