I think some of this comes down to RPGs doing a lot of abstraction for ease of play.What's always been really funny to me about people getting SO MAD about strong, brutish halflings being possible is that they canonically exist in Tolkien (c.f. Bullroarer Took etc.). Like:
Y'all trying to tell me Bullroarer here didn't have 20 STR? Because I'm pretty sure that's something you need 20 STR or more to to.
So, frankly, guys, if Tolkien could and did imagine super-strong halflings, and he's held up by you guys as this "gold standard", why is there a problem? Seriously, please explain!
(Also "You guys, I need to take my fantasy seriously, like Tolkien, and strong halflings stop me!!!" well maybe click on Golfimbul's name right there and see how seriously Tolkien took stuff.)
Some people interpret those abstractions as absolute, while others see them as relative.
If you're an absolutist in your interpretation, then having a halfling with 20 strength (the same as the half giant in the party) may seem absurd, as that would imply that this halfling has super-strength (not explicitly impossible for a fantasy game, but something one would expect to be worthy of mention in their write up).
If you're a relativist, it's much easier to contextualize, since the halfling is as strong as the half giant, relative to their respective sizes. Meaning the half giant is in an absolute sense stronger than the halfling. Game mechanics rarely do a good job of supporting this interpretation, beyond encumbrance.
Ultimately, RPGs use abstraction to simplify a lot of the "simulated reality" that the games are based in. I don't think anyone reasonable would take issue with a really muscular halfling. Some folks do, however, take issue with a halfling who'd be an even match for The Mountain (GoT) in a wrestling contest. And I don't doubt that there are folks who prefer the idea of their 20 Strength halfling being an even match for The Mountain. IMO, there's no perfect answer, or at least I haven't one.
